[PATCH v3 0/9] spi: pxa2xx: Drop linux/spi/pxa2xx_spi.h

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

As Arnd suggested we may drop linux/spi/pxa2xx_spi.h as most of
its content is being used solely internally to SPI subsystem
(PXA2xx drivers). Hence this refactoring series with the additional
win of getting rid of legacy documentation.

Note, that we have the only user of a single plain integer field
in the entire kernel for that. Switching to software nodes does not
diminish any of type checking as we only pass an integer.

On top of that it includes the previously sent "spi: pxa2xx: Cleanup
(part 2)" series that makes effort to clean up even more things.

Changelog v3:
- added new patches that were previously sent separately
  (20240403171550.1074644-1-andriy.shevchenko@linux.intel.com)
- extended cover letter a bit to explain that the replacement is
  not worse than the current approach
- v2: 20240327193138.2385910-1-andriy.shevchenko@linux.intel.com

Changelog v2:
- dropped applied patches
- added patch to amend dependencies (Mark)
- amended the second patch accordingly (Mark)
- elaborated purpose of the patch 6 in the commit message (Mark)
- v1: 20240326181027.1418989-1-andriy.shevchenko@linux.intel.com
