drivers: gpio_imx: add support for pin validation

Browse source 
Add the common config structure as a prefix of the driver-specific
config structure and use the devicetree GPIO pin counts to initialize
it.  Not all aliases appear to be present, but using instances breaks
because the ports used by different boards do not always start with
the first.
