Subject: [PATCH 3/3] extcon: intel-cht-wc: Add support for Lenovo Yoga Tab 3 Pro YT3-X90F

The Lenovo Yoga Tab 3 Pro YT3-X90F needs the same handling as
the Lenovo Yogabook models. That is it needs the extcon code to:

1. Control the Vbus regulator and USB-role-switch for the micro-USB
   port's host/device mode switching.
2. Register a power_supply device so that the charger-chip driver can
   see what sort of charger (SDP/CDP/DCP) is connected.
