[PATCHv2 3/8] gpio: ppc44x: Use module platform driver helper for GPIO

Replace the open-coded arch initcall registration with
module_platform_driver(). The initcall level changes from
arch_initcall to device_initcall, which is safe since the
driver no longer needs architecture-specific ordering.

Added MODULE info as a result, otherwise these warnings appear

ERROR: modpost: missing MODULE_LICENSE() in drivers/gpio/gpio-ppc4xx.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/gpio/gpio-ppc4xx.o
