Subject: OMAP: VRFB: convert vrfb to platform device

This patch converts vrfb library into a platform device, in an effort to
remove omap dependencies.

The platform device is registered in arch/arm/plat-omap/fb.c and
assigned resources depending on whether running on omap2 or omap3.

The vrfb driver will parse those resources and use them to access vrfb
configuration registers and the vrfb virtual rotation areas.

Subject: OMAP: move arch/arm/plat-omap/include/plat/vrfb.h

Now that vrfb driver is not omap dependent anymore, we can move vrfb.h
from arch/arm/plat-omap/include/plat to include/video/omapvrfb.h.

Subject: OMAPDSS: VRFB: add omap_vrfb_supported()

Add an exported function omap_vrfb_supported() which returns true if the
vrfb driver has been loaded succesfully. This can be used to decide if
VRFB can be used or not.
