Subject: irqchip: orion: clear bridge cause register on init
From: Sebastian Hesselbarth <sebastian.hesselbarth@xxxxxxxxx>
commit 7b119fd1bdc59a8060df5b659b9f7a70e0169fd6 upstream.
It is good practice to mask and clear pending irqs on init. We already
mask all irqs, so also clear the bridge irq cause register.
