[PATCH v2] omap: fix build when MTD_NAND_OMAP2 and TOUCHSCREEN_ADS7846 are disabled

[mike@compulab.co.il (Mike Rapoport)]

Commits 5e6a64b36ce346b7a2d481ef9fa315290eb28e5e (omap: move detection of
NAND CS to common-board-devices) and 96974a249b0cf3537f49115a59be67e2c54f315c
(omap: consolidate touch screen initialization among different boards)
break compilation when CONFIG_MTD_NAND_OMAP2 and
CONFIG_TOUCHSCREEN_ADS7846 are not selected.
Removing ifdefs and stubs from common-board-devices.h fixes the problem.

Hope this one is better.
