Timo Alho ab3dd9cc24 gpio: max77620: Fix interrupt handling 
The interrupt-related register fields on the MAX77620 GPIO controller
share registers with GPIO related fields. If the IRQ chip is implemented
with regmap-irq, this causes the IRQ controller code to overwrite fields
previously configured by the GPIO controller code.

Two examples where this causes problems are the NVIDIA Jetson TX1 and
Jetson TX2 boards, where some of the GPIOs are used to enable vital
power regulators. The MAX77620 GPIO controller also provides the USB OTG
ID pin. If configured as an interrupt, this causes some of the
regulators to be powered off.
