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.

Add compatible strings for the Cypress cypd6129 and cypd6229 dual
Type-C PD controllers to the of_device_id match table, matching the
corresponding dt-bindings update.
