Subject: [PATCH 4/7] gpio: brcmstb: correct the configuration of level interrupts

This commit corrects a bug when configuring the GPIO hardware for
IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH interrupt types. The
hardware is now correctly configured to support those types.

Fixes: 19a7b6940b78 ("gpio: brcmstb: Add interrupt and wakeup source support")
