ARM: s3c: crag6410: use generic device properties for gpio-mmio

The GPIO device in crag6410 is registered with struct bgpio_pdata passed
as platform_data to the gpio-mmio driver. We want to remove the
bgpio_pdata from the kernel and the gpio-mmio driver is now also able to
get the relevant values from the software node. Set up device properties
and switch to using platform_device_info to register the device as
platform_add_devices() doesn't allow us to pass device properties to the
driver model.
