Add several firmware files for r8169 NIC found on recent rk3588 boards

This should prevent throwing out "possible missing firmware"

those are tiny compared to the stuff we already have in, so should be fine.

that said, "possible missing firmware" messages come because this driver supports some chip variants we don't have in the boards we support, so it is really about silencing the message, not actually enabling anything.
