Subject: [PATCH v4 0/4] Fix up Nokia 770 regression

A recent change to use dynamic GPIO base allocation in the
OMAP GPIO driver caused a regression in some OMAP1 boards.
This series fixes up the Nokia 770 board from 2005:
https://en.wikipedia.org/wiki/Nokia_770_Internet_Tablet

I don't know how urgent the fix is, you decide. For me,
it is fair if fringe systems get fixed in due time, as
they are hardly anyones main development laptop.

Changes in v4:
- Fix up the polarity issues identified by Dmitry.
- Fix all erronous device trees as well.
- Link to v3: https://lore.kernel.org/r/20230430-nokia770-regression-v3-0-a6d0a89ffa8b@linaro.org

Changes in v3:
- Fix a compile error in the ADS7846 driver by dropping some
  leftover OF ifdeffery.
- Link to v2: https://lore.kernel.org/r/20230430-nokia770-regression-v2-0-984ed3ca5444@linaro.org

Changes in v2:
- Thoroughly rewrote the approach taken for the ADS7846 touchscreen
  following Dmitry's ambition to go a step further and take a swnode
  approach to this conversion: I'm fine with that, the patch just
  get a bit bigger.
- Picked up Ulf's ACK on the MMC patch.
- Link to v1: https://lore.kernel.org/r/20230430-nokia770-regression-v1-0-97704e36b094@linaro.org
