Merge tag 'ixp4xx-arm-soc-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into arm/soc

This is a major chunk of IXP4xx modernization:

- Fist we move some registers around to make room for
  the predetermined PCI I/O space.

- Then we add some Kconfig options to make it possible
  to use the old PCI driver in parallell with the new
  shiny one.

- Then we add the new PCI driver and some bindings for
  it.

- On top of this we add an (ages old) patch from Arnd
  that centralize the CPU/SoC detection in drivers/soc
  and make the header a standard Linux header to avoid
  the <mach/*> business in drivers.

- Then we split out and modernize some platform data
  headers for pata, and hwrandom, and top it up with
  DT bindings and support for hwrandom.
