drm/dp: Add drm_dp_psr_setup_time()
Add a small helper to parse the PSR setup time from the DPCD PSR capabilities and return the value in microseconds. v2: Don't waste so many bytes on the psr_setup_time_us[] table Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
