drm/amdgpu: Add dcdebugmask option to enable DPIA trace
[Why & How]
It's useful to be able to enable DPIA trace with dcdebugmask
option, especially to debug DPIA issues involved in transition
of system power states.
This patch adds an option to amdgpu.dcdebugmask to be picked up
by amdgpu DM to enable DPIA trace.

drm/amdgpu/vkms: relax timer deactivation by hrtimer_try_to_cancel
In below thousands of screen rotation loop tests with virtual display
enabled, a CPU hard lockup issue may happen, leading system to unresponsive
and crash.
do {
xrandr --output Virtual --rotate inverted
xrandr --output Virtual --rotate right
xrandr --output Virtual --rotate left
xrandr --output Virtual --rotate normal
} while (1);
NMI watchdog: Watchdog detected hard LOCKUP on cpu 1
So CPU1 stucks in hrtimer_cancel as timer callback is running endless on
current clock base, as that timer queue on CPU2 has no chance to finish it
because of failing to hold the lock. So NMI watchdog will throw the errors
after its threshold, and all later CPUs are impacted/blocked.
So use hrtimer_try_to_cancel to fix this, as disable_vblank callback
does not need to wait the handler to finish. And also it's not necessary
to check the return value of hrtimer_try_to_cancel, because even if it's
-1 which means current timer callback is running, it will be reprogrammed
in hrtimer_start with calling enable_vblank to make it works.
v2: only re-arm timer when vblank is enabled (Christian) and add a Fixes
tag as well
v3: drop warn printing (Christian)
v4: drop superfluous check of blank->enabled in timer function, as it's
guaranteed in drm_handle_vblank (Christian)

drm/amd/display: only accept async flips for fast updates
Up until now, amdgpu was silently degrading to vsync when
user-space requested an async flip but the hardware didn't support
it.
The hardware doesn't support immediate flips when the update changes
the FB pitch, the DCC state, the rotation, enables or disables CRTCs
or planes, etc. This is reflected in the dm_crtc_state.update_type
field: UPDATE_TYPE_FAST means that immediate flip is supported.
Silently degrading async flips to vsync is not the expected behavior
from a uAPI point-of-view. Xorg expects async flips to fail if
unsupported, to be able to fall back to a blit. i915 already behaves
this way.
This patch aligns amdgpu with uAPI expectations and returns a failure
when an async flip is not possible.

drm/i915: use mock device info for creating mock device
Instead of modifying the device info on the fly, use static const mock
device info.
It's not okay to modify device info at runtime; we've added separate
runtime info for info that needs to be modified at runtime. We've added
safeguards to device info to prevent it from being modified, but commit 5e352e32aec2 ("drm/i915: preparation for using PAT index") just cast the
const away and modified it anyway. This prevents device info from being
moved to rodata.
