Merge tag 'aspeed-6.18-devicetree-0' of https://git.kernel.org/pub/scm/linux/kernel/git/bmc/linux into soc/dt

Early ASPEED devicetree updates for 6.18

Notable changes:

- Meta's Wedge400 and Fuji boards have had parallel devicetrees added for a
  transition to a new static flash layout. The original layout is deprecated and
  I anticipate removing related devicetrees in future releases.

New platforms:

- Darwin (Meta)

  Darwin is Meta's rack switch platform with an AST2600 BMC integrated for
  health monitoring purpose.

Updates and fixes:

- GB200NVL (Nvidia): Networking, I2C, regulators, GPIOs
- Wedge400, Fuji (Meta): Fix warnings from devicetree bindings
- Use fixed-layout for NVMEM on Asrock platforms
- Various: minor fixes for warnings from FSI devicetree bindings
