[PATCH v2, 1/2] dt-bindings: connector: Add time property for sender response

[joswang <joswang1221@gmail.com>]

From: Jos Wang <joswang@lenovo.com>

Add "pd2-sender-response-time-ms" and "pd3-sender-response-time-ms"
DT attributes to better solve the following test items in the usb
pd compliance test:
  TEST.PD.PROT.SRC3.2 SenderResponseTimer Timeout
  TEST.PD.PROT.SNK.6 SenderResponseTimer Timeout

This is to enable setting of platform/board specific timer values as
these timers have a range of acceptable values.
