Subject: [PATCH v6] extcon: palmas: Added a new compatible type *ti,palmas-usb-vid*

The Palmas device contains only a USB VBUS-ID detector, so added a
compatible type *ti,palmas-usb-vid*. Didn't remove the existing compatible
types for backward compatibility.

Changes from v5:
* Fixed documentation

Changes from v4:
* added compatible property "ti,twl6035-usb-vid"

Changes from v3:
* Fixed commit log message (VID to VBUS-ID).
* Fixed the Documentation to tell "ti,twl6035-usb" and "ti,palmas-usb" is
deprecated
Changes from [1]:
* Since the old compatible values will be in 3.11 kernel, we shouldn't remove
the old compatible values. So retain the old compatible values.
