hwspinlock: provide implementation to reset a spinlock
hwspinlocks shared between the mpu and a remote processor can be
left in a locked state in the event of a device exception on the
remote processor have taken a hwspinlock.
The mpu being the master of the remote processor, is the best
choice to try and unlock the hwspinlock.
A new API __hwspin_lock_reset is added to allow the mpu to unlock
or reset a hwspinlock.
