[PATCH u-boot] 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.
