[PATCH v2 0/2] ARM: dts: aspeed: Add ASRock Rack B650D4U support

This series adds initial device tree support for the ASRock Rack
B650D4U BMC, which is based on the ASPEED AST2600 SoC.

The B650D4U is a server motherboard for AMD Ryzen processors. The initial
DTS describes the BMC console, FMC flash, dedicated management Ethernet,
FRU EEPROM, and watchdog.

The dedicated management port is described as MAC0 connected to an external
Clause 22 PHY on MDIO0 at address 0. The MAC uses RGMII with RX internal
delay, matching the vendor DTB description.

Tested:
- Built aspeed-bmc-asrock-b650d4u.dtb
- Ran dtbs_check for the board/aspeed binding
- QEMU boot smoke-tested with ast2600-evb

Changes in v2:
- Added MDIO0 PHY node for the dedicated management port.
- Set mac0 phy-mode to rgmii-rxid and added phy-handle.
- Removed unused GPIO include from the DTS.
