locking, powerpc: Annotate uic->lock as raw
uic->lock is protecting the interrupt controller hardware. This lock
can not be preempted on -rt.
In mainline this change documents the low level nature of
the lock - otherwise there's no functional difference. Lockdep
and Sparse checking will work as usual.
