Subject: [PATCH v2 1/2] dt-bindings: connector: usb: add accessory mode description

Add description of the USB-C Accessory Modes supported on the particular
USB-C connector. This is required for devices like Qualcomm SM8150-HDK,
which have no other way to express accessory modes supported by the
hardware platform.
