powerpc/imc-pmu: Use the correct spinlock initializer.

Browse Source 
[ Upstream commit 007240d59c ]

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.
