[PATCH v2 00/15] gpio: replace legacy bgpio_init() with its modernized alternative - part 4

[Bartosz Golaszewski]

Here's the final part of the generic GPIO chip conversions. Once all the
existing users are switched to the new API, the final patch in the
series removes bgpio_init(), moves the gpio-mmio fields out of struct
gpio_chip and into struct gpio_generic_chip and adjusts gpio-mmio.c to
the new situation.

Down the line we could probably improve gpio-mmio.c by using lock guards
and replacing the - now obsolete - "bgpio" prefix with "gpio_generic" or
something similar but this series is already big as is so I'm leaving
that for the future.

Tested in qemu on vexpress-a9.
