Ezequiel Garcia fc8cd2ac0a watchdog: orion: Use atomic access for shared registers ...

Since the timer control register is shared with the clocksource driver,
use the recently introduced atomic_io_clear_set() to access such register.
Given the watchdog core already provides serialization for all the
watchdog ops, this commit allows to remove the spinlock entirely.
