gpio: loongson: Create a dynamic platform device

Browse source

It is pretty helpful to create some kind of device for backing the
GPIO chips, especially when preparing the driver for using
GENERIC_GPIO, so let's create a simple platform device and a simple
platform device driver and create the gpiochip in the .probe() routine
for the device driver. Keep all at the core initcall so the behaviour
is the same as before.
