[PATCH v2 1/3] dt-bindings: usb: ti,tps6598x: add TPS66993 compatible

[Radhey Shyam Pandey]

Add a ti,tps66993 compatible to explicitly identify TPS66993 devices.
The TPS66993 is not host-interface compatible with TPS6598x, so a distinct
compatible is required.

On the AMD/Xilinx VEK385 Evaluation Board, the Texas Instruments TPS66993
acts as the USB Type-C/USB PD DRP controller for the MMI USB interface,
handling CC signaling, connection detection, PD negotiation and power/data
role swapping.

Changes for v2:
- Rename the compatible to match the exact device (ti,tps66993) and in
  commit mention the usage of TPS66993 chip on VEK385 Evaluation Board.
