of: Fix locking vs. interrupts
The OF code uses irqsafe locks everywhere except in a handful of functions for no obvious reasons. Since the conversion from the old rwlocks, this now triggers lockdep warnings when used at interrupt time. At least one driver (ibmvscsi) seems to be doing that from softirq context. This converts the few non-irqsafe locks into irqsafe ones, making them consistent with the rest of the code.
