ARM: OMAP2+: Fix regression for using local timer on non-SMP SoCs
On am437x we use also an ARM timer in addition to the dmtimer. As am437x
is not an SMP SoC, we need tick_broadcast() implemented. With the recent
dmtimer changes, Arnd started to see link failures for non-SMP am437x
configuration:
kernel/time/tick-broadcast.o: in function `tick_device_uses_broadcast':
tick-broadcast.c:(.text+0x130): undefined reference to `tick_broadcast'
Let's fix the issue by reverting dmtimer related changes that started
building timer.c only for CONFIG_SOC_HAS_REALTIME_COUNTER. We still
always need timer.c built-in for omap5 and dra7 for timer_probe().
And let's also move am437x tick_broadcast() to board-generic.c as
that's where we now call timer_probe() for am437x. This way we avoid
adding back more ifdefs to timer.c.
Fixes: 2ee04b88547a ("ARM: OMAP2+: Drop old timer code for dmtimer and 32k counter")
