[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.

[How]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
   to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
   with DCN and sends reply back in an outbox1 message triggering an
   outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
   synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
   inbox1 message and waits for a conditional variable (CV) which will be
   signaled by outbox1 ISR.
3) DM will retrieve Outbox1 message and send back reply to upper layer
   and complete the AUX command

drm/amd/display: Fix two cursor duplication when using overlay

Our driver supports overlay planes, and as expected, some userspace
compositor takes advantage of these features. If the userspace is not
enabling the cursor, they can use multiple planes as they please.
Nevertheless, we start to have constraints when userspace tries to
enable hardware cursor with various planes. Basically, we cannot draw
the cursor at the same size and position on two separated pipes since it
uses extra bandwidth and DML only run with one cursor.

For those reasons, when we enable hardware cursor and multiple planes,
our driver should accept variations like the ones described below:

  +-------------+   +--------------+
  | +---------+ |   |              |
  | |Primary  | |   | Primary      |
  | |         | |   | Overlay      |
  | +---------+ |   |              |
  |Overlay      |   |              |
  +-------------+   +--------------+

In this scenario, we can have the desktop UI in the overlay and some
other framebuffer attached to the primary plane (e.g., video). However,
userspace needs to obey some rules and avoid scenarios like the ones
described below (when enabling hw cursor):

                                      +--------+
                                      |Overlay |
 +-------------+    +-----+-------+ +-|        |--+
 | +--------+  | +--------+       | | +--------+  |
 | |Overlay |  | |Overlay |       | |             |
 | |        |  | |        |       | |             |
 | +--------+  | +--------+       | |             |
 | Primary     |    | Primary     | | Primary     |
 +-------------+    +-------------+ +-------------+

 +-------------+   +-------------+
 |     +--------+  |  Primary    |
 |     |Overlay |  |             |
 |     |        |  |             |
 |     +--------+  | +--------+  |
 | Primary     |   | |Overlay |  |
 +-------------+   +-|        |--+
                     +--------+

If the userspace violates some of the above scenarios, our driver needs
to reject the commit; otherwise, we can have unexpected behavior. Since
we don't have a proper driver validation for the above case, we can see
some problems like a duplicate cursor in applications that use multiple
planes. This commit fixes the cursor issue and others by adding adequate
verification for multiple planes.

Change since V1 (Harry and Sean):
- Remove cursor verification from the equation.

Commit 4192f7b57689 ("drm/amdgpu: unmap register bar on device init
failure") makes amdgpu_driver_unload_kms() skips amdgpu_device_fini(),
so the VGA clients remain registered. So when
vga_arbiter_notify_clients() iterates over registered clients, it causes
NULL pointer dereference.

Since there's no reason to register VGA clients that early, so solve
the issue by putting them after all the goto cleanups.

v2:
 - Remove redundant vga_switcheroo cleanup in failed: label.

drm/amd/display: Reject non-zero src_y and src_x for video planes

[Why]
This hasn't been well tested and leads to complete system hangs on DCN1
based systems, possibly others.

The system hang can be reproduced by gesturing the video on the YouTube

[How]
Reject atomic commits with non-zero drm_plane_state.src_x or src_y values.

 - Add code comment describing the reason we're rejecting non-zero
   src_x and src_y
 - Drop gerrit Change-Id
 - Add stable CC
 - Based on amd-staging-drm-next
