Re: [PATCH v2 1/3] dt-bindings: chrome: Add Cros EC UCSI driver

PDCs are "Power Delivery Controllers". It refers to an IC which
manages PD communication for a USB-C port. UCSI stands for "USB Type-C
Connector System Software Interface". It is a specification maintained
by the USB-IF which defines a standardized interface for communicating
with PDCs. I'll update the description in the v3 series to provide the
full name for both of these terms.

I separated these bindings because they are associated with separate
mutually exclusive drivers. But, I'm fine with adding this as a
compatibility string in google,cros-ec-typec.yaml and will make that
change in the v3 series.
