drm/format-helper: Merge drm_fb_memcpy() and drm_fb_memcpy_toio()
Merge drm_fb_memcpy() and drm_fb_memcpy_toio() into a drm_fb_memcpy()
that uses struct iosys_map for buffers. The new function also supports
multi-plane color formats. Convert all users of the original helpers.
v2:
* rebase onto refactored mgag200
* use drm_formap_info_bpp() (Sam)
* do static init in hyperv and mgag200 (Sam)
* update documentation (Sam)
* add TODO on vaddr location (Sam)
