irqchip: atmel-aic-common: Prevent clobbering of priority when changing IRQ type

Browse source

commit 91d1179212 upstream.

This patch makes the bitmask for AIC_SRCTYPE consistent
with that of its valid values, and prevents the priority
field at bits 2:0 from being clobbered by an incorrect
AND with the AIC_SRCTYPE mask.
