drm/display: Add missing Adaptive Sync DPCD definitions
The missing DPCD definitions from DP2.0 spec is as follows:
DOWNSPREAD_CTRL (107h):
FIXED_VTOTAL_AS_SDP_EN_IN_PR_ACTIVE (bit 6)
For sink devices that support Adaptive-Sync operation
and Panel Replay
DPRX_FEATURE_ENUMERATION_LIST_CONT_1 (2214h):
ADAPTIVE_SYNC_SDP_SUPPORTED (bit 0)
Bit to check sink device has Adaptive-Sync capability
AS_SDP_FIRST_HALF_LINE_OR_3840_PIXEL_CYCLE_WINDOW_NOT_SUPPORTED (bit 1)
A sink device that clears this bit will generate VSync pulse
leading edge of the HDMI output on the line count at which
Adaptive-Sync SDP is received as long as source device transmits
Adaptive-Sync SDP either in first line or first 3840 pixel cycles
of the line whichever occurs first.
VSC_EXT_SDP_FRAMEWORK_VERSION_1_SUPPORTED (bit 4)
Bit to check sink device has SDP framework version 1 capability
