[Intel-gfx] [PATCH 2/6] drm/atomic: Unconditionally call prepare_fb.

[Maarten Lankhorst]

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.
