net: stmmac: dwmac-meson8b: add support for the RGMII RX delay on G12A
Amlogic Meson G12A (and newer: G12B, SM1) SoCs have a more advanced RX
delay logic. Instead of fine-tuning the delay in the nanoseconds range
it now allows tuning in 200 picosecond steps. This support comes with
new bits in the PRG_ETH1[19:16] register.
Add support for validating the RGMII RX delay as well as configuring the
register accordingly on these platforms.
