Subject: [PATCH] [WATCHDOG] mv64x60_wdt: Rework the timeout register
 manipulation

Consolidate the timeout config register modification into a single
function.  Also, use the enabled flag in the config register to
determine whether the timer is enabled instead of a separately
maintained flag, MV64x60_WDOG_FLAG_ENABLED.

Add spinlock protection around enabling/disabling the watchdog timer.
