Separate the memory region from the framebuffer device a little bit.
It's now possible to select the memory region used by the framebuffer
device using the new mem_idx parameter of omapfb_plane_info. If the
mem_idx is specified it will be interpreted as an index into the
memory regions array, if it's not specified the framebuffer's index is
used instead. So by default each framebuffer keeps using it's own
memory region which preserves backwards compatibility.
This allows cloning the same memory region to several overlays and yet
each overlay can be controlled independently since they can be
associated with separate framebuffer devices.

Previously the only place to get the size of the display was from the
DSS's sysfs interface, making, for example, configuring overlays and doing
updates on manual displays more difficult.

Split arch/arm/plat-omap/include/mach/omapfb.h into two files:
include/linux/omapfb.h - ioctls etc for userspace and some kernel
stuff for board files
drivers/video/omap/omapfb.h - for omapfb internal use
This cleans up omapfb.h and also makes it easier for the upcoming new
DSS driver to co-exist with the old driver.
