====================
Add the dwmac driver support for T-HEAD TH1520 SoC

This series adds support for dwmac gigabit ethernet in the T-Head TH1520
RISC-V SoC used on boards like BeagleV Ahead and the LicheePi 4A.

The gigabit ethernet on these boards does need pinctrl support to mux
the necessary pads. The pinctrl-th1520 driver, pinctrl binding, and
related dts patches are in linux-next. However, they are not yet in
net-next/main.

Therefore, I am dropping the dts patch for v5 as it will not build on
net-next/main due to the lack of the padctrl0_apsys pin controller node
in next-next/main version th1520.dtsi. It does exist in linux-next [1]
and the two patches in this series allow the ethernet ports to work
correctly on the LPi4A and Ahead when applied to linux-next.

The dwmac-thead driver in this series does not need the pinctrl-th1520
driver to build. Nor does the thead,th1520-gmac.yaml binding need the
pinctrl binding to pass the schema check.
