Subject: [PATCH 2/2] net: ethernet: nb8800: handle all RGMII declinations

Commit a999589ccaae ("phylib: add RGMII-ID interface mode definition")
and commit 7d400a4c5897 ("phylib: add PHY interface modes for internal
delay for tx and rx only") added several RGMII declinations:
PHY_INTERFACE_MODE_RGMII_ID, PHY_INTERFACE_MODE_RGMII_RXID and
PHY_INTERFACE_MODE_RGMII_TXID to deal with internal delays.

Those are all RGMII modes (1Gbit) and must be considered that way when
setting the MAC Mode or the Pads Mode for the HW to work properly.
