arm64: perf: don't warn about missing interrupt-affinity property for PPIs
 
PPIs are affine by nature, so the interrupt-affinity property is not
used and therefore we shouldn't print a warning in its absence.

 * lib/bust_spinlocks.c

 * Provides a minimal bust_spinlocks for architectures which don't have one of their own.

 * bust_spinlocks() clears any spinlocks which would prevent oops, die(), BUG()
