dwc3-msm: Don't override USB speed with EUD based spoof connect/detach 



EUD may be used concurrently with USB Superspeed, however the EUD
notification handler currently overrides USB speed as high speed.
As a result, dwc3_msm_suspend() would incorrectly skip suspending
SS PHY. Fix this issue by removing USB speed override functionality
with EUD notification handler.
