This patch series introduces the initial Device Tree support for the
Facebook Anacapa BMC platform, which is based on the Aspeed AST2600 SoC.
It configures the platform-specific peripherals and aliases for OpenBMC
usage.

The series is comprised of two patches:
1. Adds the compatible string for the board to the binding documentation.
2. Adds the main Device Tree Source file for the Anacapa BMC.

Changes in v8:
* Dropped the unused 'pcc_memory' reserved memory region as suggested
by Andrew Jeffery.
* Reordered the 'spi-gpio' properties to group all '-gpios' properties
together for better readability (Andrew Jeffery).
* Moved the 'pinctrl_ncsi3_default' pinctrl group from the board DTS
file to 'arch/arm/boot/dts/aspeed-g6.dtsi' (assuming this dtsi
change is applied separately or already in the base) to make it
available for other platforms (Andrew Jeffery).
* Revised the 'gpio-line-names' for better clarity and alignment with
schematic signal names, avoiding confusion with pin-muxed functions
(Andrew Jeffery).
* Improved the formatting and readability of 'sgpio-line-names' list.
* Removed the unused 'led-2' definition from the 'leds' node.
* Added support for the ADC128D818 sensor to the I2C bus.
* No functional changes in the binding patch (1/2).
* Added clarification for mixed-case signal names (Andrew Jeffery):
The mixed-case names (e.g., FM_CPU0_SYS_RESET_N) in gpio-line-names
are chosen to directly match the signal names used in the hardware
schematics.
This convention is used to maintain strict adherence and clarity when
cross-referencing between the Device Tree and the board design documents.
