basic_mmio_gpio: split into a gpio library and platform device
Allow GPIO_BASIC_MMIO_CORE to be used to provide an accessor library
for implementing GPIO drivers whilst abstracting the register access
detail. Based on a patch from Anton Vorontsov[1] and adapted to allow
bgpio_chip to be embedded in another structure.
Changes since v1:
- Register the gpio_chip in the platform device probe
