IXP4xx driver updates for modernizing the IXP4xx platforms,
taregeted for v5.15:

- Add DT bindings to the expansion bus and PATA libata driver.

- Add a new expansion bus driver.

- Rewrite the watchdog driver to use the watchdog core and
  spawn from the timer (clocksource) driver.

- Refactor the PATA/libata driver to probe from the device
  tree and use the expansion bus driver to manipulate chip
  select timings directly.
