Subject: irqchip/atmel-aic: Fix wrong bit operation for IRQ priority

From: Milo Kim <[email protected]>

commit 49f34134aea74f19ca016f055d25ee55ec359dee upstream.

Atmel AIC has common structure for SMR (Source Mode Register).

bit[6:5] Interrupt source type
bit[2:0] Priority level
Other bits are unused.

To update new priority value, bit[2:0] should be cleared first and then new priority level can be written. However, aic_common_set_priority() helper clears source type bits instead of priority bits. This patch fixes wrong mask bit operation.
