Merge tag 'apple-soc-drivers-6.18' of https://git.kernel.org/pub/scm/linux/kernel/git/sven/linux into soc/drivers

Apple SoC driver updates for 6.18

Krzysztof Kozlowski asked us to move away from generic compatibles:
- Adjust all dt-bindings to use apple,t8103-XXXX instead of apple,XXXX
  as fallback and add a comment that the old generic list should no
  longer be extended.
- Add new fallback compatibles to pinctrl, pmdomain, spi, and mca
  drivers. These changes have been Acked by their subsystem maintainers
  to be merged through our tree together with the dt-bindings.

Support for pre-M1 Apple Silicon:
- SART and mailbox gain support for Apple's A11, which are both
  required for NVMe.
- NVMe also gains support for Apple's A11 and the nvme maintainers
  prefer that we merge this through the soc tree together with
  the mailbox and SART changes.
- SPMI compatibles for A11 and T2 have been added, also going through
  the soc tree due to conflicts with the generic compatible removal and
  because no driver change is required.
