drm/amd/display: Fix max vstartup calculation for modes with borders

[Why]
Vertical and horizontal borders in timings are treated as increasing the
active area - vblank and hblank actually shrink.

Our input into DML does not include these borders so it incorrectly
assumes it has more time than available for vstartup and tmdl
calculations for some modes with borders.

An example of such a timing would be 640x480@72Hz:

h_total: 832
h_border_left: 8
h_addressable: 640
h_border_right: 8
h_front_porch: 16
h_sync_width: 40
v_total: 520
v_border_top: 8
v_addressable: 480
v_border_bottom: 8
v_front_porch: 1
v_sync_width: 3
pix_clk_100hz: 315000

[How]
Include borders as part of destination vactive/hactive.

This change DCN20+ so it has wide impact, but the destination vactive
and hactive are only really used for vstartup calculation anyway.

Most modes do not have vertical or horizontal borders.

drm/amd/display: Reduce delay when sink device not able to ACK 00340h write

[Why]
Theoretically, per DP 1.4a spec, sink device needs to AUX_ACK 00340h
write. However, due to hardware limitation, some sink devices have no
00340h dpcd address at all. This results in sink side fails to reply
ACK, and consequently cause source side keep retrying DPCD write on DPCD
00340h. This results in significant delay when DPCD 00340h write is
triggered (e.g. at S3 resume).

[How]
Check whether sink device could ACK on DPCD 00340h write on boot. If
sink device fails to ACK, then remember that, so we won't write to DPCD
00340h later on.

There will be a drm.debug KMS level message to inform user once a 00340h
DPCD write is skipped on purpose.

drm/amdgpu: Read clock counter via MMIO to reduce delay (v5)

[Why]
GPU timing counters are read via KIQ under sriov, which will introduce
a delay.

[How]
It could be directly read by MMIO.

v2: Add additional check to prevent carryover issue.
v3: Only check for carryover for once to prevent performance issue.
v4: Add comments of the rough frequency where carryover happens.
v5: Remove mutex and gfxoff ctrl unused with current timing registers.

drm/amdgpu: Avoid printing of stack contents on firmware load error

In case when psp_init_asd_microcode() fails to load ASD microcode file,
psp_v12_0_init_microcode() tries to print the firmware filename that
failed to load before bailing out.

This is wrong because:

- the firmware filename it would want it print is an incorrect one as
  psp_init_asd_microcode() and psp_v12_0_init_microcode() are loading
  different filenames
- it tries to print fw_name, but that's not yet been initialized by that
  time, so it prints random stack contents, e.g.

    amdgpu 0000:04:00.0: Direct firmware load for amdgpu/renoir_asd.bin failed with error -2
    amdgpu 0000:04:00.0: amdgpu: fail to initialize asd microcode
    amdgpu 0000:04:00.0: amdgpu: psp v12.0: Failed to load firmware "\xfeTO\x8e\xff\xff"

Fix that by bailing out immediately, instead of priting the bogus error
message.

drm/amdgpu: Fix resource leak on probe error path

This reverts commit 4192f7b5768912ceda82be2f83c87ea7181f9980.

It is not true (as stated in the reverted commit changelog) that we never
unmap the BAR on failure; it actually does happen properly on
amdgpu_driver_load_kms() -> amdgpu_driver_unload_kms() ->
amdgpu_device_fini() error path.

What's worse, this commit actually completely breaks resource freeing on
probe failure (like e.g. failure to load microcode), as
amdgpu_driver_unload_kms() notices adev->rmmio being NULL and bails too
early, leaving all the resources that'd normally be freed in
amdgpu_acpi_fini() and amdgpu_device_fini() still hanging around, leading
to all sorts of oopses when someone tries to, for example, access the
sysfs and procfs resources which are still around while the driver is
gone.
