irqchip/irq-brcmstb-l2: Set IRQ_LEVEL for level triggered interrupts
[ Upstream commit 94debe03e8afa1267f95a9001786a6aa506b9ff3 ]
When support for the level triggered interrupt controller flavor was
added with c0ca7262088e, we forgot to update the flags to be set to
contain IRQ_LEVEL. While the flow handler is correct, the output from
/proc/interrupts does not show such interrupts as being level triggered
when they are, correct that.
Fixes: c0ca7262088e ("irqchip/brcmstb-l2: Add support for the BCM7271 L2 controller")
