I'm working on removing the fields relevant only to gpio-mmio from
struct gpio_chip. One of the bits that need addressing before we can do
this is the removal of struct bgpio_pdata from the kernel. Fortunately
there are only 3 users left treewide.

This series adds support for parsing of generic device properties to
gpio-mmio, converts all users to setting up software nodes containing
relevant values in their property sets and removes struct bgpio_pdata.

As for merging: it would be best for MFD/OMAP/s3c maintainers to ack the
changes and let me route them through the GPIO tree. I can provide an
immutable tag if needed.

Obviously I was only able to build-test the changes so any actual
verification is appreciated.

Changes in v2:
- add a comment about the gpio-mmio-specific property not being suitable
  for device-tree
- pick up tags
- Link to v1: https://lore.kernel.org/r/20250624-gpio-mmio-pdata-v1-0-a58c72eb556a@linaro.org
