dwc3-msm: Force USB speed as high speed if SS release lane is called

DP driver shall call SS release lane API asynchronously when USB is into
device mode or host mode or not yet started. This is possible as ADSP
firmware notification over UCSI may be delayed and can be running in
parallel with altmode functionality. Hence force maximum speed as USB
high speed if SS release lane API is called until next USB able disconnect.
