drm: renesas: shmobile: Atomic conversion part 1
Implement atomic mode setting for both the primary and overlay planes.
This involves:
- Moving the primary plane handling code from CRTC mode setting to
plane handling shared by primary and overlay planes,
- Adding basic CRTC and mode config atomic mode setting ops, which
don't do much yet.
