mb/intel/tglrvp/variants/tglrvp_up4 - Enable onboard HDMI and type-C displays for TGL-Y RVP
- Enable DDC pins for DDI-B
- Enable HPD pins for DDI-1/DDI-2
- Update MPHY/USB2 Mapping to match with the TGL-Y RVP schematic
BUG: System not able to detect displays attached to onboard micro-HDMI or Type-C connectors
TEST: hot-plug/unplug HDMI displays with onboard micro-HDMI connector and USB Type-C connectors to make sure the displays get detected and enabled
