[PATCH 5/7] drm/cirrus: phase 3: use atomic .set_config helper

[John Hunter <zhjwpku@gmail.com>]

From: Zhao Junwang <zhjwpku@gmail.com>

Now that phase 1 and phase 2 are completed, switch .set_config
helper to use the atomic one.

-stop looking legacy crtc->primary->fb, instead we should use
crtc->primary->state->fb

.prepare() calls are no more needed, remove them
.mode_set() and .mode_set_base are no longer needed, remove
