usb: typec: tcpm: Relax disconnect threshold during power negotiation
If the voltage is being decreased in power negotiation, the Source will
set the power supply to operate at the new voltage level before sending
PS_RDY. Relax the threshold before sending Request Message so that it
will not race with Source which begins to adjust the voltage right after
it sends Accept Message (PPS) or tSrcTransition (25~35ms) after it sends
Accept Message (non-PPS).
The real threshold will be set after Sink receives PS_RDY Message.
