powerpc/imc-pmu: Use the correct spinlock initializer.
[ Upstream commit 007240d59c11f87ac4f6cfc6a1d116630b6b634c ]
The macro __SPIN_LOCK_INITIALIZER() is implementation specific. Users
that desire to initialize a spinlock in a struct must use
__SPIN_LOCK_UNLOCKED().
Use __SPIN_LOCK_UNLOCKED() for the spinlock_t in imc_global_refc.
