[PATCH] omap4: Enable ARM local timers with OMAP4430 es1.0

[Santosh Shilimkar]

exception

On OMAP4430 ES1.0 the local timers are gated by security. Enable the
CONFIG_LOCAL_TIMERS for omap2plus build and handle the OMAP4430 es1.0
exception case.

This patch has dependency on the first patch in this series.
