drm/mediatek: Convert to atomic_create_state

Browse source

The mediatek crtc implementation provides a custom reset hook.
However, this hook only allocates the state, initializes it with
__drm_atomic_helper_crtc_reset(), and frees the previous state. It
does not perform any hardware reset.

Since this is exactly what the atomic_create_state hook is meant to
do, minus the old state cleanup which the caller handles, convert the
implementation to use atomic_create_state with
__drm_atomic_helper_crtc_state_init() instead.
