uboot-airoha: fix ethernet on Nokia XG-040G-MD

U-Boot v2026.07 ships arch/arm/dts/an7581-u-boot.dtsi, which declares
gdm1 with status = "disabled". That file is appended to the end of the
board DTS, so it overrides the MAC enabled by the board and U-Boot ends
up without a network device:

  No ethernet found.

Add a board specific an7581-nokia-xg-040g-md-u-boot.dtsi re-enabling
gdm1. U-Boot only pulls in the first matching *-u-boot.dtsi (firstword
in scripts/Makefile.lib), so the board file must include the SoC one
explicitly, otherwise the entire an7581 U-Boot glue is dropped along
with it: uart1 bootph-all, the eth/pcs/snfi/mmc nodes and the ATF
reserved memory. Same approach as en7581-evb and Nokia Valyrian.

Tested on Nokia XG-040G-MD: TFTP recovery boot works again.
