ARM: BCM5301X: Ignore another (BCM4709 specific) fault code
Broadcom ARM devices seem to generate some fault once per boot. We already have an ignoring handler for BCM4707/BCM4708, but BCM4709 generates different code. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
