drm/format-helper: Export drm_fb_clip_offset()
Provide a function that computes the offset into a blit destination
buffer. This will allow to move destination-buffer clipping into the
format-helper callers.
v4:
* add missing '@' for parameter documentation
* fix typo 'frambuffer'
v2:
* provide documentation (Sam)
* return 'unsigned int' (Sam, Noralf)
