Subject: [PATCH v1 2/3] dt-bindings: usb: maxim,max33359.yaml: add usage of
 sink bc12 time property

Add usage of "sink-bc12-completion-time-ms"  connector property to
max33359 controller for delaying PD negotiation till BC1.2 detection
completes. This overcomes the occasional delays observed while
receiving PD messages where BC1.2 detection runs in parallel.
