Boris Brezillon 805f0c2609 irqchip/atmel-aic: Fix potential deadlock in ->xlate() 
commit 5eb0d6eb3fac3daa60d9190eed9fa41cf809c756 upstream.

aic5_irq_domain_xlate() and aic_irq_domain_xlate() take the generic chip
lock without disabling interrupts, which can lead to a deadlock if an
interrupt occurs while the lock is held in one of these functions.

Replace irq_gc_{lock,unlock}() calls by
irq_gc_{lock_irqsave,unlock_irqrestore}() ones to prevent this bug from
happening.

Fixes: b1479ebb77 ("irqchip: atmel-aic: Add atmel AIC/AIC5 drivers")
