irqchip/gic-v2: Reset APRn registers at boot time Booting a crash kernel while in an interrupt handler is likely to leave the Active Priority Registers with some state that is not relevant to the new kernel, and is likely to lead to erratic behaviours such as interrupts not firing as their priority is already active. As a sanity measure, wipe the APRs clean on startup. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
