powerpc/kcsan: Properly instrument arch_spin_unlock()
The following boottime error is encountered with SMP kernel:
kcsan: improperly instrumented type=(0): arch_spin_unlock(&arch_spinlock)
kcsan: improperly instrumented type=(0): spin_unlock(&test_spinlock)
kcsan: improperly instrumented type=(KCSAN_ACCESS_WRITE): arch_spin_unlock(&arch_spinlock)
kcsan: improperly instrumented type=(KCSAN_ACCESS_WRITE): spin_unlock(&test_spinlock)
kcsan: improperly instrumented type=(KCSAN_ACCESS_WRITE | KCSAN_ACCESS_COMPOUND): arch_spin_unlock(&arch_spinlock)
kcsan: improperly instrumented type=(KCSAN_ACCESS_WRITE | KCSAN_ACCESS_COMPOUND): spin_unlock(&test_spinlock)
kcsan: selftest: test_barrier failed
kcsan: selftest: 2/3 tests passed
Kernel panic - not syncing: selftests failed
Properly instrument arch_spin_unlock() with kcsan_mb().
