This adds a DWMAC glue driver for the PRG_ETHERNET registers found in
Meson8b and GXBB SoCs. Based on the "old" meson6b-dwmac glue driver
the register layout is completely different.
Thus I introduced a separate driver.
Changes since v1:
- make clkin1 mandatory because the internal mux expects two clocks
(in other words: this makes the driver consistent with how the
hardware actually works)
- expose the MPLL2 clock for use by DT so we can pass it to the ethmac
- added a .remove function to the glue driver which disables and
unprepares the clocks on driver removal
