video: Add i.MX23/28 framebuffer driver
changes since v2:
- use v3 and v4 for specifying the ip version instead of i.MX23/28.
This is a better namespace when future versions are added.
- rename mach/fb.h to mach/mxsfb.h
changes since v1:
- Add a LCDC_ prefix to the register names.
- use set/clear registers where appropriate
- protect call to mxsfb_disable_controller() in mxsfb_remove()
with a (host->enabled) as suggested by Lothar Wassmann
