irqchip/irq-brcmstb-l2: Set IRQ_LEVEL for level triggered interrupts 

When support for the level triggered interrupt controller flavor was
added with c0ca726208, 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: c0ca726208 ("irqchip/brcmstb-l2: Add support for the BCM7271 L2 controller")
