Move the ppc4xx gpio driver out of arch/powerpc/platforms/44x/ into
drivers/gpio/gpio-ppc4xx.c. The driver has no architecture-specific
dependencies and follows the same pattern as other PowerPC GPIO
drivers already in drivers/gpio/ (e.g. gpio-mpc8xxx, gpio-mpc5200).

- Renamed Kconfig symbol from PPC4xx_GPIO to GPIO_PPC4XX
- Updated ppc44x_defconfig and warp_defconfig to use the new symbol
- Marked the new option as tristate (was bool) since the driver
  supports module build via module_platform_driver()
- Added COMPILE_TEST support. Needs PPC as clrbits32 is in use.
