irq_domains are necessary to support interrupt chip drivers with
the Device Tree. In addition, by registering with irq_domains,
other irq chip drivers on the system will respect the virq
allocations made by this driver.
The msm-gpio specification requires two interrupt-cells. The
first specifies the irq chip hwirq, and the second is a default
irq type configuration for the interrupt. It's still possible to
override the default configuration with request_irq() if one
chooses to.

GPIO support for Qualcomm SOCs requires interaction with the
radio (baseband processor). This API allows the different boards
to enable GPIO through the radio processor in a generic way.
