QMP V3 UNI PHY is a single lane USB3 PHY without support for DisplayPort (DP). Main difference from DP combo QMPv3 PHY is that UNI PHY doesn't have dual RX/TX lanes and no separate DP_COM block for configuration related to type-c or DP. While at it, fix has_pwrdn_delay attribute for USB-DP PHY configuration.
