net: dwc_eth_xgmac_socfpga: Add support for rgmii-id mode.

An issue was identified where selecting the phy-mode as
rgmii-id in the device tree source (DTS) would cause the
`dwc_eth_xgmac_socfpga` driver to raise an unsupported phy mode error.

From the MAC controller's perspective, the rgmii and rgmii-id
phy modes are effectively identical. To address this, both
modes will now be configured to rgmii in the MAC controller.

This change ensures that the rgmii-id phy mode is properly
supported without error.
