drm/tidss: Set crtc modesetting parameters with adjusted mode

[ Upstream commit cfb29225db20c56432a8525366321c0c09edfb2e ]

TIDSS uses crtc_* fields to propagate its registers and set the
clock rates. So set the CRTC modesetting timing parameters with
the adjusted mode when needed, to set correct values.
