genirq: Provide irq_gc_{lock_irqsave,unlock_irqrestore}() helpers
[ Upstream commit ebf9ff753c041b296241990aef76163bbb2cc9c8 ]
Some irqchip drivers need to take the generic chip lock outside of the
irq context.
Provide the irq_gc_{lock_irqsave,unlock_irqrestore}() helpers to allow
one to disable irqs while entering a critical section protected by
gc->lock.
Note that we do not provide optimized version of these helpers for !SMP,
because they are not called from the hot-path.
[ tglx: Added a comment when these helpers should be [not] used ]
