Clocksource driver selection

ATMEL_CLOCKSOURCE_PIT

Periodic Interval Timer (PIT) support

Select this to get a clocksource based on the Atmel Periodic Interval
Timer. It has a relatively low resolution and the TC Block clocksource
should be preferred.

ATMEL_CLOCKSOURCE_TCB

Timer Counter Blocks (TCB) support

Select this to get a high precision clocksource based on a
TC block with a 5+ MHz base clock rate.
On platforms with 16-bit counters, two timer channels are combined
to make a single 32-bit timer.
It can also be used as a clock event device supporting oneshot mode.
