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.
[ tglx: Folded the equivivalent fix for atmel-aic ]
