Subject: [PATCH] ARM: omap2: drop broken broadcast timer hack

The OMAP4 timer code had a special hack for using the broadcast timer
without SMP. Since the dmtimer is now gone, this also needs to be dropped
to avoid a link failure for non-SMP AM43xx configurations:

kernel/time/tick-broadcast.o: in function `tick_device_uses_broadcast':
tick-broadcast.c:(.text+0x130): undefined reference to `tick_broadcast'

Fixes: 2ee04b88547a ("ARM: OMAP2+: Drop old timer code for dmtimer and 32k counter")
