ARM: OMAP2+: Fix fallout from localtimer divorce and SMP=n

A recent patch ef3160c (ARM: OMAP2+: Divorce from local timer API,
2013-03-04) broke the omap build when SMP=n because the TWD functions
are only compiled on SMP=y builds. Stub out the TWD calls when the TWD
isn't built in to to keep everything building.

arch/arm/mach-omap2/built-in.o: In function `omap4_local_timer_init':
dss-common.c:(.init.text+0x1d90): undefined reference to `twd_local_timer_register'
