Add common gpio functionalities across qualcomm soc targets.
This common gpio driver would allow the consumers to be able to
configure gpio function, set/get gpio direction as input/output,
configure the gpio as pull-up/pull-down, configure the gpio as an
IRQ and also query the gpio irq status.
The GPIO pin definition would be SoC specific.
