[PATCH v6 2/6] arm64: dts: rockchip: describe PCIe RTL8125 Ethernet on ROCK 5 family

[Ricardo Pardini via B4 Relay]

From: Ricardo Pardini <ricardo at pardini.net>

The Radxa ROCK 5B, 5B+ and 5T carry an on-board Realtek RTL8125 NIC
behind pcie2x1l2; the ROCK 5T has a second one behind pcie2x1l1.

Describe the PCI function nodes and attach ethernet0 (and, on the
ROCK 5T, ethernet1) aliases, so that U-Boot's fdt_fixup_ethernet() can
fill in their MAC addresses from its ethaddr/eth1addr environment.

The shared NIC goes in rk3588-rock-5b-5bp-5t.dtsi, the ROCK 5T's second
NIC in rk3588-rock-5t.dts.
