drm/amdgpu: Set FreeSync state using drm VRR properties
Support for AMDGPU specific FreeSync properties and ioctls are dropped
from amdgpu_dm in favor of supporting drm variable refresh rate
properties.
The notify_freesync and set_freesync_property functions are dropped
from amdgpu_display_funcs.
The drm vrr_capable property is now attached to any DP/HDMI connector.
Its value is updated accordingly to the connector's FreeSync capabiltiy.
The freesync_enable logic and ioctl control has has been dropped in
favor of utilizing the vrr_enabled on the drm CRTC. This allows for more
fine grained atomic control over which CRTCs should support variable
refresh rate.
To handle state changes for vrr_enabled it was easiest to drop the
forced modeset on freesync_enabled change. This patch now performs the
required stream updates when planes are flipped.
This is done for a few reasons:
(1) VRR stream updates can be done in the fast update path
(2) amdgpu_dm_atomic_check would need to be hacked apart to check
desired variable refresh state and capability before the CRTC
disable pass.
(3) Performing VRR stream updates on-flip is needed for enabling BTR
support.
VRR packets and timing adjustments are now tracked and compared to
previous values sent to the hardware.
