Some drm drivers call remove_conflicting_framebuffers. Create a
drm_fb_helper function that wraps around these calls.
This is part of an effort to prevent drm drivers from calling fbdev
functions directly, in order to make fbdev emulation a top level drm
option.
v2:
- Added kerneldocs
- Follow the drm way of aligning of arguments in func definitions
