usb: typec: tcpm: Add support for sink-bc12-completion-time-ms DT property

Add support for parsing DT time property "sink-bc12-completion-time-ms".
This timer is used to relax the PD state machine during Sink attach to
allow completion of Battery Charging (BC1.2) charger type detection in
TCPC before PD negotiations. BC1.2 detection is a hardware mechanism to
detect charger port type that is run by some controllers (such as
"maxim,max33359") in parallel to Type-C connection state machines.
This is to ensure that BC1.2 completes before PD is enabled as running
BC1.2 in parallel with PD negotiation results in delays violating timer
constraints in PD spec.

This is an optional timer and will not add any delay unless explicitly
set.
