Subject: [PATCH 2/2] ARM: omap: timers: reduce rating of gp_timer clocksource

From: Grygorii Strashko <grygorii.strashko@...com>

Now ARM Global timer (rating 300) will not be selected as clocksource,
because it's initialized after OMAP GP Timer (rating 300) and
Timekeeping core will not allow to replace clocksource with new one if
both of them have the same rating.

Reduce rating of OMAP GP Timer (300->290) when it's used as
clocksource device - this will allow to select ARM Global timer (300)
as clocksource when enabled.
