[PATCH v3 1/2] dt-bindings: usb: cypress,cypd4226: Add cypd6129/cypd6229 support

[Akash Kumar <akash.kumar@oss.qualcomm.com>]

From: Akash Kumar <akakum@qti.qualcomm.com>

Extend the binding to cover the Cypress cypd6129 and cypd6229 dual
Type-C PD controllers, which share the same I2C-controlled interface
as the cypd4226. Also add pinctrl and wakeup-source properties, and
relax reg/interrupts constraints that only applied to cypd4226.
