Maarten Lankhorst eeee74a4f6 drm/atomic: Unconditionally call prepare_fb. 
Atomic drivers may set properties like rotation on the same fb, which
may require a call to prepare_fb even when framebuffer stays identical.

Instead of handling all the special cases in the core, let the driver
decide when prepare_fb and cleanup_fb are noops.

This is a revert of:

commit fcc60b413d
Author: Keith Packard <keithp@keithp.com>
Date:   Sat Jun 4 01:16:22 2016 -0700

    drm: Don't prepare or cleanup unchanging frame buffers [v3]

The original commit mentions that this prevents waiting in i915 on all
previous rendering during cursor updates, but there are better ways to
fix this.
