[PATCH 02/41] drm/rockchip: Get rid of some unnecessary code

[Sean Paul]

From: Tomasz Figa <tfiga at chromium.org>

Current code implements prepare_fb and cleanup_fb callbacks only to
grab/release fb references, which is already done by atomic framework
when creating/destryoing plane state. Also there are some unused fields
vop and vop_win structs. Let's remove these unused bits.
