Merge tag 'apple-soc-dt-6.17' of https://git.kernel.org/pub/scm/linux/kernel/git/sven/linux into soc/dt

Apple SoC device tree changes for v6.17

- Added the bindings and nodes for Apple SoC GPU. The driver itself
  isn't ready for upstreaming yet due to rust dependencies but we're
  confident that the bindings are stable at this point.
- Added a missing node for the touchbar framebuffer to Apple T2 device
  trees, which is the BMC for some x86 Macs
- Fixed a W=1 warning by adding bit offsets to NVMEM node names. This
  required a change to the generic NVMEM cell binding which will be part
  of 6.17 through the NVMEM tree.
