Subject: [PATCH] clocksource: timer-sun5i: Switch to sched_clock_register()

The 32 bit sched_clock interface supports 64 bits since 3.13-rc1.
Upgrade to the 64 bit function to allow us to remove the 32 bit
registration interface.

Cc'in Ingo because this is simple enough to probably just apply to timers/core
