drm/amd/display: Fix DP MST sinks removal issue

[Why]
In USB4 DP tunneling, it's possible to have this scenario that
the path becomes unavailable and CM tears down the path a little bit late.
So, in this case, the HPD is high but fails to read any DPCD register.
That causes the link connection type to be set to sst.
And not all sinks are removed behind the MST branch.

[How]
Restore the link connection type if it fails to read DPCD register.

drm/mcde: Do not use dirty GEM FB handling

This driver has no way to handle damage, the reason the
drm_gem_fb_create_with_dirty() was used was because I had the
ambition that the driver would only send out updates to DSI
command displays whenever something changed, so as to
minimize traffic.

It turns out this ambition with command mode isn't working
in practice because all the MCDE does is to create a
continuous stream of DSI commands and while it is possible to
send single frame updates with it, it's not been worthwhile.
So we are just setting up continuous updates.

drm/fbdev-dma: Implement fbdev emulation for GEM DMA helpers

Implement fbdev emulation that is optimized for drivers that use
DMA helpers. The buffers may no tbe moveable, may not require damage
handling and have to be located in system memory. This allows fbdev
emulation to operate directly on the buffer and mmap it to userspace.

Besides those constraints, the emulation works like in the generic
code. As an internal DRM client provides, it receives hotplug, restore
and unregister events. The DRM client is independent from the fbdev
probing, which runs on the first successful hotplug event.

The emulation is part of the DMA helper module and not build unless
DMA helpers and fbdev emulation has been configured.

Tested with vc4.

drm/amdgpu/vcn: Disable indirect SRAM on Vangogh broken BIOSes

The VCN firmware loading path enables the indirect SRAM mode if it's
advertised as supported. We might have some cases of FW issues that
prevents this mode to working properly though, ending-up in a failed
probe. An example below, observed in the Steam Deck:

[...]
[drm] failed to load ucode VCN0_RAM(0x3A)
[drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0000)
amdgpu 0000:04:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring vcn_dec_0 test failed (-110)
[drm:amdgpu_device_init.cold [amdgpu]] *ERROR* hw_init of IP block <vcn_v3_0> failed -110
amdgpu 0000:04:00.0: amdgpu: amdgpu_device_ip_init failed
amdgpu 0000:04:00.0: amdgpu: Fatal error during GPU init
[...]

Disabling the VCN block circumvents this, but it's a very invasive
workaround that turns off the entire feature. So, let's add a quirk
on VCN loading that checks for known problematic BIOSes on Vangogh,
so we can proactively disable the indirect SRAM mode and allow the
HW proper probe and VCN IP block to work fine.

drm/amd/display: Fix HDCP failing to enable after suspend

[Why]
On resume some displays are not ready for HDCP, so they will fail if we
start the hdcp authentintication too soon.

Add a delay so that the displays can be ready before we start.

NOTE: Previoulsy this delay was set to 3 seconds but it was causing
issues with compliance, 2 seconds should enough for compliance and the
s3 resume case.

[How]
Change the Delay to 2 seconds.

drm/amd/pm: Fix sienna cichlid incorrect OD volage after resume

Always setup overdrive tables after resume. Preserve only some
user-defined settings in user_overdrive_table if they're set.

Copy restored user_overdrive_table into od_table to get correct
values.

On cold boot, BTC was triggered and GfxVfCurve was calibrated. We
got VfCurve settings (a). On resuming back, BTC will be triggered
again and GfxVfCurve will be recalibrated. VfCurve settings (b)
got may be different from those of cold boot.  So if we reuse
those VfCurve settings (a) got on cold boot on suspend, we can
run into discrepencies.
