The cycles clocksource is a higher resolution than the gptimer one, so
make sure the ratings field reflects this.

For systems where the core cycles are not a usable tick source (like SMP
or cycles gets updated), enable gptimer0 as an alternative.

Pass clocksource pointer to the read() callback for clocksources.  This
allows us to share the callback between multiple instances.

Impact: change calling convention of existing clock_event APIs

struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.

Another single-patch change.  For safety, we BUG_ON() in
clockevents_register_device() if it's not set.
