Add documentation for the cros-ec-ucsi device tree definition. Defining this node will load the cros_ec_ucsi driver which is used for USB-C port control on PDC based ChromeOS systems. Additionally, update mantainers list to reflect changes to the ChromeOS USB owners.

This node is intended to allow the host to read and control the Type C ports.
