[PATCH 1/7] drm/ch7006: Stop using drm_crtc_force_disable

The correct way for legacy drivers to update properties that need to
do a full modeset, is to do a full modeset.

Note that we don't need to call the drm_mode_config_internal helper
because we're not changing any of the refcounted paramters.
