Merge tag 'aspeed-6.20-devicetree-0' of https://git.kernel.org/pub/scm/linux/kernel/git/bmc/linux into soc/dt

First batch of ASPEED Arm devicetree changes for 6.20

New platforms:

- NVIDIA MSX4 BMC

  The NVIDIA MSX4 HPM (host platform module) is a reference board for
  managing up to 8 PCIe connected NVIDIA GPUs via ConnectX-8 (CX8)
  SuperNICs. The BMC manages all GPUs and CX8s for both telemetry and
  firmware update via MCTP over USB. The host CPUs are dual socket Intel
  Granite Rapids processors.

  For more detail on this architecture:

  https://developer.nvidia.com/blog/nvidia-connectx-8-supernics-advance-ai-platform-architecture-with-pcie-gen6-connectivity/

Updated platforms:

- ast2600-evb (ASPEED): Various tidy-ups to address binding warnings
- bletchley (Meta): Watchdog fix, tidy-ups to address binding warnings
- clemente (Meta): HDD LED fix, GPIO line names, EEPROMs
- harma (Meta): fanboard presence GPIO
- santabarbara (Meta): IPMB, GPIO line names, additional IO expander
