drm/format-helper: Provide drm_fb_blit()
Provide drm_fb_blit() that works with struct iosys_map. Update all
users of drm_fb_blit_toio(), which required a destination buffer in
I/O memory.
This patch only updates the function's interface. The implementation
still relies on the destination buffer to be located in I/O memory.
See the follow-up patches for implementational changes. The new
function's interface works with multi-plane color formats, but again
implementation only supports a single plane for now.
v2:
* rebase onto refactored simpledrm
* use IOSYS_MAP_INIT_VADDR() (Sam)
* update the commit message on the use of I/O memory (Sam)
