[PATCH] OMAP2: CONFIG_TOUCHSCREEN_ADS7846 XOR CONFIG_MTD_NAND_OMAP2 breaks build

[Matthias Scheer <scheer@in.tum.de>]

#ifdef clauses in arch/arm/mach-omap2/common-board-devices.h header file broke
kernel build when configured with CONFIG_TOUCHSCREEN_ADS7846 (XOR)
CONFIG_MTD_NAND_OMAP2

quick and dirty fix by using #ifdef clauses in the code file, too
