Revert "soc: qcom: Use a deferrable timer base for the msm watchdog"

This reverts commit bccd8899.

Watchdog timer is not disabled by hw when CPU went into idle.
Change watchdog timer to a deferrable timer will keep cpu from waking
up while all cores are idle which is a false positive. So change the
watchdog timer back to the normal timer.
