bcm2712: add kmod-r8169 and kmod-usb-net-rtl8152

Boards such as [1] and [2] add an extra Ethernet port to Raspberry Pi (CM)5.
These typically use Realtek PCIe or USB Ethernet NICs. Include kmod-r8169 and
kmod-usb-net-rtl8152 by default to make it easy to configure LAN/WAN ports
with these parts on Raspberry Pi 5.

Because CM5 can fit in the same carrier boards as CM4, also ensure that both
devices have the same Ethernet NIC kmods.
