[PATCH 1/3] dt-bindings: usb: Add Cypress cypd6129/cypd6229 Type-C controller

[Akash Kumar]

Add the device-tree binding documentation for the Cypress cypd6129
and cypd6229 dual Type-C PD controllers. These are used on Shikra
CQM/CQS/IQS platforms to handle usb-role-switch for the USB Type-C
ports over an I2C interface, similarly to the existing cypd4226
binding.

cypd6229 is a variant of cypd6129 and is described with a
"cypress,cypd6129" fallback compatible string.
