irqchip/atmel-aic[5]: Fix incorrect lock guard conversion
Commit b00bee8afaca ("irqchip: Convert generic irqchip locking to guards") replaced calls to irq_gc_lock_irq{save,restore}() with guard(raw_spinlock_irq). However, in irq-atmel-aic5.c and irq-atmel-aic.c, the xlate callback is used in the early boot process, before interrupts are initially enabled. As its destructor enables interrupts, this triggers the warning in start_kernel(): WARNING: CPU: 0 PID: 0 at init/main.c:1024 start_kernel+0x4d0/0x5dc Interrupts were enabled early Fix this by using guard(raw_spinlock_irqsave) instead.
