[PATCH 09/23] drm/i915/vrr: Compute vrr vsync if platforms support it

[Ankit Nautiyal]

Previously, TRANS_VRR_VSYNC was exclusively used for panels with
adaptive-sync SDP support in VRR scenarios. However, to drive fixed refresh
rates using the VRR Timing generator, we now need to program
TRANS_VRR_VSYNC regardless of adaptive sync SDP support. Therefore, let's
remove the adaptive sync SDP check and program TRANS_VRR_VSYNC for
platforms where VRR timing generator is used.
