[PATCH 4/7] gpio: ppc44x: Use platform resource helper for GPIO MMIO

Map the PPC44x GPIO register block through the platform device
resource instead of reparsing the firmware node directly.

The GPIO node now probes as a platform device, so use the
platform helper to keep resource handling aligned with the converted
driver model and to report mapping failures with the platform device
context.
