Geert Uytterhoeven 9b81018185 arm64: dts: renesas: rcar-gen3: Convert EtherAVB to explicit delay handling
Some EtherAVB variants support internal clock delay configuration, which
can add larger delays than the delays that are typically supported by
the PHY (using an "rgmii-*id" PHY mode, and/or "[rt]xc-skew-ps"
properties).

Historically, the EtherAVB driver configured these delays based on the
"rgmii-*id" PHY mode.  This was wrong, as these are meant solely for the
PHY, not for the MAC.  Hence properties were introduced for explicit
configuration of these delays.

Convert the R-Car Gen3 DTS files from the old to the new scheme:
  - Add default "rx-internal-delay-ps" and "tx-internal-delay-ps"
    properties to the SoC .dtsi files, to be overridden by board files
    where needed,
  - Convert board files from "rgmii-*id" PHY modes to "rgmii", adding
    the appropriate "rx-internal-delay-ps" and/or "tx-internal-delay-ps"
    overrides.

Notes:
  - R-Car E3 and D3 do not support TX internal delay handling,
  - On R-Car D3, TX internal delay handling must always be enabled,
    hence this fixes a bug on Draak,
  - On R-Car V3H, RX internal delay handling must always be enabled.
