usb: dwc3-msm: Disable RxTerm Detection by Core in U3 state

Before suspending SS-PHY RxTerm detection must be disabled,
and enabled after resuming SS-PHY as recommended in databook.
If this is not performed then Core detects RxTerm removal after
U3 exit which results in SS device getting disconnected.
After bus resume is complete some devices seem to re-establish
SS connection and enumerate where as some device do not enumerate
at all.
