Leonard Crestez 9f19fd3bd8 drm/mxsfb: Switch to drm_atomic_helper_commit_tail_rpm ... The lcdif block is only powered on when display is active so plane updates when not enabled are not valid. Writing to an unpowered IP block is mostly ignored but can trigger bus errors on some chips. Prevent this situation by switching to drm_atomic_helper_commit_tail_rpm and having the drm core ensure atomic_plane_update is only called while the crtc is active. This avoids having to keep track of "enabled" bits inside the mxsfb driver. This also requires handling the vblank event for disable from mxsfb_pipe_disable.
