Check the UCSI_CAP_GET_PD_MESSAGE bit before sending GET_PD_MESSAGE to
discover partner and cable identity, check UCSI_CAP_CABLE_DETAILS before
sending GET_CABLE_PROPERTY to discover the cable and check
UCSI_CAP_ALT_MODE_DETAILS before registering the a cable plug. Additionally,
move 8 bits from reserved_1 to features in the ucsi_capability struct. This
makes the field 16 bits, still 8 short of the 24 bits allocated for it in
UCSI v3.0, but it will not overflow because UCSI only defines 14 bits in
bmOptionalFeatures.
