drm: Introduce drm_framebuffer_{get,put}()

Browse source 
For consistency with other reference counting APIs in the kernel, add
drm_framebuffer_get() and drm_framebuffer_put() to reference count DRM
framebuffers.

Compatibility aliases are added to keep existing code working. To help
speed up the transition, all the instances of the old functions in the
DRM core are already replaced in this commit.

The existing semantic patch for the DRM subsystem-wide conversion is
extended to account for these new helpers.
