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.

description:
Chrome OS devices have an Embedded Controller(EC) which has access to
Type C port state. This node is intended to allow the host to read and
control the Type C ports. The node for this device should be under a
- cros-ec node like google,cros-ec-spi.
+ cros-ec node like google,cros-ec-spi. On TCPC systems, ChromeOS should
+ use cros-ec-typec. On PDC systems, ChromeOS should use cros-ec-ucsi.
