rockchip64-6.19: arm64: dts: rockchip: describe pcie ethernets on FriendlyElec NanoPC-T6

Browse Source 
- By fully describing the pcie hardware for the RTL8125s (rtl8169) present on the
  board, we get to alias them to ethernet0/1. In return, (mainline) u-boot will by
  default patch the runtime FDT though it's fdt_fixup_ethernet() implementation,
  hopefully resulting in fully stable MAC addresses without the need to program
  the RTL NIC's EEPROM; as an added benefit, u-boot MAC & kernel MAC would match,
  facilitating network-boot setups.

NanoPC-T6
By fully describing the pcie hardware for the RTL8125s (rtl8169) present on the
board, we get to alias them to ethernet0/1. In return, (mainline) u-boot will by
default patch the runtime FDT though it's fdt_fixup_ethernet() implementation,
hopefully resulting in fully stable MAC addresses without the need to program
the RTL NIC's EEPROM; as an added benefit, u-boot MAC & kernel MAC would match,
facilitating network-boot setups.
