drm: Add devm_drm_dev_alloc macro
Add a new macro helper to combine the usual init sequence in drivers,
consisting of a kzalloc + devm_drm_dev_init + drmm_add_final_kfree
triplet. This allows us to remove the rather unsightly
drmm_add_final_kfree from all currently merged drivers.
The kerneldoc is only added for this new function. Existing kerneldoc
and examples will be udated at the very end, since once all drivers
are converted over to devm_drm_dev_alloc we can unexport a lot of
interim functions and make the documentation for driver authors a lot
cleaner and less confusing. There will be only one true way to
initialize a drm_device at the end of this, which is going to be
devm_drm_dev_alloc.

drm/dp_mst: Kill the second sideband tx slot, save the world
While we support using both tx slots for sideband transmissions, it
appears that DisplayPort devices in the field didn't end up doing a very
good job of supporting it. From section 5.2.1 of the DP 2.0
specification:
There are MST Sink/Branch devices in the field that do not handle
interleaved message transactions.
To facilitate message transaction handling by downstream devices, an
MST Source device shall generate message transactions in an atomic
manner (i.e., the MST Source device shall not concurrently interleave
multiple message transactions). Therefore, an MST Source device shall
clear the Message_Sequence_No value in the Sideband_MSG_Header to 0.
This might come as a bit of a surprise since the vast majority of hubs
will support using both tx slots even if they don't support interleaved
message transactions, and we've also been using both tx slots since MST
was introduced into the kernel.
However, there is one device we've had trouble getting working
consistently with MST for so long that we actually assumed it was just
broken: the infamous Dell P2415Qb. Previously this monitor would appear
to work sometimes, but in most situations would end up timing out
LINK_ADDRESS messages almost at random until you power cycled the whole
display. After reading section 5.2.1 in the DP 2.0 spec, some closer
investigation into this infamous display revealed it was only ever
timing out on sideband messages in the second TX slot.
Sure enough, avoiding the second TX slot has suddenly made this monitor
function perfectly for the first time in five years. And since they
explicitly mention this in the specification, I doubt this is the only
monitor out there with this issue. This might even explain explain the
seemingly harmless garbage sideband responses we would occasionally see
with MST hubs!
So - rewrite our sideband TX handlers to only support one TX slot. In
order to simplify our sideband handling now that we don't support
transmitting to multiple MSTBs at once, we also move all state tracking
for down replies from mstbs to the topology manager.

Revert "drm/dp_mst: Remove single tx msg restriction."
This reverts commit
6bb0942e8f46863a745489cce27efe5be2a3885e.
Unfortunately it would appear that the rumors we've heard of sideband
message interleaving not being very well supported are true. On the
Lenovo ThinkPad Thunderbolt 3 dock that I have, interleaved messages
appear to just get dropped:
[drm:drm_dp_mst_wait_tx_reply [drm_kms_helper]] timedout msg send
00000000571ddfd0 2 1
[dp_mst] txmsg cur_offset=2 cur_len=2 seqno=1 state=SENT path_msg=1 dst=00
[dp_mst] type=ENUM_PATH_RESOURCES contents:
[dp_mst] port=2
DP descriptor for this hub:
OUI 90-cc-24 dev-ID SYNA3 HW-rev 1.0 SW-rev 3.12 quirks 0x0008
It would seem like as well that this is a somewhat well known issue in
the field. From section 5.4.2 of the DisplayPort 2.0 specification:
There are MST Sink/Branch devices in the field that do not handle
interleaved message transactions.
To facilitate message transaction handling by downstream devices, an
MST Source device shall generate message transactions in an atomic
manner (i.e., the MST Source device shall not concurrently interleave
multiple message transactions). Therefore, an MST Source device shall
clear the Message_Sequence_No value in the Sideband_MSG_Header to 0.
MST Source devices that support field policy updates by way of
software should update the policy to forego the generation of
interleaved message transactions.
This is a bit disappointing, as features like HDCP require that we send
a sideband request every ~2 seconds for each active stream. However,
there isn't really anything in the specification that allows us to
accurately probe for interleaved messages.
If it ends up being that we -really- need this in the future, we might
be able to whitelist hubs where interleaving is known to work-or maybe
try some sort of heuristics. But for now, let's just play it safe and
not use it.

testing coverage.
While at it:
- convert driver to use eieio() and dcbf() helpers instead of
open-coding them
- add invalid_vram_cache() helper to avoid code duplication

dt-bindings: display: convert ilitek,ili9322 to DT Schema
The .txt binding explains:
"
The following optional properties only apply to
RGB and YUV input modes and
can be omitted for BT.656 input modes:
"
This constraint is not implmented in the DT Schema.
The original binding from the .txt file referenced
properties that is included in panel-timing.yaml.
The properties in question are:
- pixelclk-active
- de-active
- hsync-active
- vsync-active
These properties was dropped in the conversion as they are not relevant.
v2:
- drop properties from panel-timing (Linus)
- drop use of spi-slave.yaml (Maxime)
- introduce unevaluatedProperties (Maxime)
- dropped unused properties (Linus)
- delete stray spaces

Several bindings specifies a "te-gpios" for tearing effect signal.
Add this to panel-common so we have a shared definition.
