Shenwei Wang 3283d820dc gpio: mxc: add runtime pm support
Add runtime PM support and allow the GPIO controller to enter
into runtime suspend automatically when not in use to save power.
However, it will automatically resume and enable clocks when a
GPIO or IRQ is requested.

While putting the GPIO module itself into power saving mode may not
have an obvious impact on current dissipation, the function is necessary
because the GPIO module disables its clock when idle. This enables the
system an opportunity to power off the parent subsystem, and this conserves
more power. The typical i.MX8 SoC features up to 8 GPIO controllers, but
most of the controllers often remain unused.
