irqchip: Convert generic irqchip locking to guards
Conversion was done with Coccinelle and a few manual fixups.
In a few interrupt chip callbacks this changes replaces
raw_spin_lock_irqsave() with a guard(raw_spinlock). That's intended and
correct because those interrupt chip callbacks are invoked with the
interrupt descriptor lock held and interrupts disabled. No point in using
the irqsave variant.
No functional change.
