drm/amd/display: change fastboot timing validation
[Why]
VBIOS light up eDP with 6bpc but driver use 8bpc without
disable valid stream then re-enable valid stream. Some
panels can't runtime change color depth.
[How]
Change fastboot timing validation function. Not only check
LANE_COUNT, LINK_RATE...etc
