Subject: [PATCH RESEND 00/14] gpio: replace legacy bgpio_init() with its
 modernized alternative

I hit a network error when sending for the first one, retrying now.

This is the first round of GPIO driver conversions to using the
modernized variant of the gpio-mmio API.

While at it: sprinkle in some additional tweaks and refactoring.
