[PATCH u-boot v2] ARM: dts: aspeed: Add Nvidia VR-NVL BMC

[Jacky Huang <jackyhuang@nvidia.com>]

Adds a dts for the NVIDIA VR-NVL BMC board, an AST2600-based BMC for
the Vera Rubin NVL platform.

MAC0 uses phy-mode = "rgmii-id" with no SoC-side clk-delay node, so it
relies on the zero default introduced by commit 3f6198c0db1c ("clk:
ast2600: set default clk-delay for all ethernet macs to 0"). With that
change in place, MAC0 brings up its MDIO bus and establishes a link
with the on-board PHY.

v2:
  - Sort the Makefile entry alphabetically.
  - Drop unused mmc0/1/2 aliases; eMMC/SD are not used on this board.
  - Drop unused ethernet1/2/3 aliases (only mac0 is enabled).
  - Drop redundant aspeed,ecc-size-mb = <0> (defaults to 0).
  - Drop unnecessary flash compatible; it defaults to jedec,spi-nor.
  - Drop the disabled spi1 flash@1 node.

v1: Message-Id: <20260624172052.752986-1-jackyhuang@nvidia.com>
