net: stmmac: dwmac-ipq806x: account for rgmii-txid/rxid/id phy-mode

Browse source

Currently the ipq806x dwmac driver is almost always used attached to the
CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii".

Some device came up with a special configuration where the PHY is
directly attached to the GMAC port and in those case phy-mode needs to
be set to "rgmii-id" to make the PHY correctly work and receive packets.

Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id"
(or variants) mode is set, the mode is rejected and probe fails.

Add support also for these phy-modes to correctly setup PHYs that requires
delay applied to tx/rx.
