ARM: OMAP: Split fb.c to remove last remaining cpu_is_omap usage
Looks like we missed plat-omap/fb.c for cpu_is_omap usage mach-omap2. This is the last user of cpu_is_omap, so let's quickly fix it up so we can finally remove plat/cpu.h for omap2lus. We want to limit cpu_is_omap macro usage to mach-omap2 only so we can make plat/cpu.h private. After this we can finally drop plat/cpu.h for omap2+.
