clocksource/drivers/fttmr010: Optimize sched_clock()
The sched_clock() call should be really fast so we want to
avoid an extra if() clause on the read path if possible.
Implement two sched_clock_read() functions, one if the timer
counts up and one if it counts down. Incidentally this also
mirrors how clocksource_mmio_init() works and make things
simple and easy to understand.
