PATCH v3 1/1 drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes.

v3:
* remove out-comented line in drm_gem_framebuffer_helper.h (Maxime)
v2:
* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
* add tutorial-style documentation
