Changes since v1:
- Changing patch version to v6 to fix version number confusion.

Changes since v6:
- Rebase on usb-next.

Changes since v7:
- Heikki's suggestion:
Moved the actual write of TCPC_VBUS_SINK_DISCONNECT_THRES
register to tcpci code.

Changes since v8:
- Moved the logic to program the default values of
  TCPC_VBUS_SINK_DISCONNECT_THRESH into the tcpci code.
