net: phy: motorcomm: Support YT8531S PHY in YT6801 Ethernet controller
YT6801's internal PHY is confirmed as a GMII-capable variant of YT8531S
by a previous series[1] and reading PHY ID. Add support for
PHY_INTERFACE_MODE_GMII for YT8531S to allow the Ethernet driver to
reuse the PHY code for its internal PHY.
