- Remove explicit clocksource setup and let it be done by OF framework

simultaneouly: previously we could only do one - as all of them had
same arc_counter_setup() routine for registration

- Setup routines also ensure that the underlying timer actually exists.

- Remove some of the panic() calls if underlying timer is NOT detcted as
a fallback clocksource might still be available
1. If GRFC doesn't exist, jiffies clocksource gets registered anyways
2. if RTC doesn't exist, TIMER1 cetainly will take over (as it is
always present)

May be it is time to move these drivers into the drivers/clocksource directory where they belong to.
