drm: omapdrm: Handle primary plane config through atomic plane ops

Use the new CRTC atomic transitional helpers drm_helper_crtc_mode_set()
and drm_helper_crtc_mode_set_base() to implement the CRTC .mode_set and
.mode_set_base operations. This delegates primary plane configuration to
the plane .atomic_update and .atomic_disable operations, removing
duplicate code from the CRTC implementation.

* HACK: The legacy set config helper drm_crtc_helper_set_config() that

* a NULL frame buffer (for instance from drm_fb_release()). As a result
* the CRTC is disabled without going through a full mode set, and the
* primary plane' framebuffer is kept pin. Unpin it manually here until
* we switch to the atomic set config helper.
