ARM: OMAP: cleanup: remove OMAP_MCBSP Kconfig warnings

When the OMAP patches are applied and the kernel is built for a
non-ARM target, there are a handful of Kconfig warnings due to the use
of OMAP_MCBSP in arch-independent Kconfig files.

This patch simply removes the 'select OMAP_MCBSP' in these
arch-independent files since it is already 'default y' in
arch/arm/plat-omap/Kconfig
