ARM: 6759/1: smp: Select local timers vs broadcast timer support runtime

The current code support of dummy timers in absence of local
timer is compile time. This is an attempt to convert it to runtime
so that on few SOC version if the local timers aren't supported
kernel can switch to dummy timers. OMAP4430 ES1.0 does suffer from
this limitation.

This patch should not have any functional impact on affected
files.
