Due to the dwmac glue layer register changed, we need to
introduce a new compatible name for the Meson-AXG SoC
to support for the RMII 100M ethernet PHY.

We need to introduce a new compatible name for the Meson-AXG SoC
in order to support the RMII 100M ethernet PHY, since the PRG_ETH0
register of the dwmac glue layer is changed from previous old SoC.

2.17.0
In the Meson-AXG SoC, the phy mode setting of PRG_ETH0 in the glue layer
is extended from bit[0] to bit[2:0].
There is no problem if we configure it to the RGMII 1000M PHY mode,
since the register setting is coincidentally compatible with previous one,
but for the RMII 100M PHY mode, the configuration need to be changed to
value - b100.
This patch was verified with a RTL8201F 100M ethernet PHY.

Looks weird to have this if target at a specific SoC withing a function named
after another SoC
Couldn't you make one function per soc type, and pass that function pointer in
the match data ?
