The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

dts: add IPQ4018/IPQ4019 ethernet MAC and ethernet switch definitions

2022-02-04T05:26:45+00:00

This adds the ethernet MAC and ethernet switch definitions.

I've rewritten the header file and the DTS based on documentation
and the required driver fields rather than the GPL'ed
ones from openwrt.

ipq4018: add TCSR definitions from Linux.

2021-10-18T19:18:01+00:00

These are hardware configuration options which are required in
the linux/openwrt device trees for the IPQ4018/IPQ4019 devices.

Since this isn't obtained from linux upstream but instead from
openwrt, this can't go in contrib; instead it is going in
sys/dts/include/ .

Obtained from: OpenWRT

Tested:

* IPQ4019 ASUS RT-AC58U AP, initial bootstrapping
