ARM: OMAP: build mach-omap code only if needed 

If we build a kernel with CONFIG_ARCH_OMAP2PLUS enabled but all of the
individual SoCs disabled, we run into a large number of link errors
because if incorrect dependencies:

arch/arm/mach-omap2/built-in.o: In function `_add_initiator_dep':
arch/arm/mach-omap2/omap_hwmod.c:691: undefined reference to `clkdm_add_sleepdep' arch/arm/mach-omap2/built-in.o: In function `_del_initiator_dep':

We can avoid this if we make CONFIG_ARCH_OMAP2PLUS a silent option that
gets enabled any time that one of the SoC versions is enabled.
