arch/arm/plat-omap/fb.c contains code to alloc omapfb buffers at early boot time according to information given from the bootloader or board file. This code isn't currently used by any board, and is anyway something that the newer vram.c could handle. So remove the alloc code and in later patches make old omapfb driver use vram.c.
