Buildfailure for omap3_defconfig due to patch OMAP: RX51: Add LCD Panel support

Hi Roger,

I just wanted to inform you that your Patch
OMAP: RX51: Add LCD Panel support (b499d77834ae292465f8d06bb0a88f1a647dfa1a) 
introduces a build failure for the omap3_defconfig.

You can see the error message here:
http://kisskb.ellerman.id.au/kisskb/buildresult/2601981/

This is due to the fact that omap3_defconfig has
CONFIG_MACH_NOKIA_RX51=y
set which enables the compilation of arch/arm/mach-omap2/board-rx51.c

board-rx51.c calls rx51_video_mem_init in arch/arm/mach-omap2/board-rx51-
video.c which is guarded by 
#if defined(CONFIG_FB_OMAP2) || defined(CONFIG_FB_OMAP2_MODULE)

Unfortunately none if them is set in the omap3_defconfig.

Would be nice if you could fix this :)

Thanks,
Peter
