[PATCH 3/8] drm/bochs: stop looking at legacy state

[John Hunter]

From: Zhao Junwang <zhjwpku at gmail.com>

with transitional helpers we've used the new callbacks, but control
flow was still old, but with atomic first step is to call atomic_check,
then prepare_fb, and so on, by this time, we can not look at any legacy
state like plane->fb or crtc->enabled, because they are updated at the
very end.
