--------------------------------

[ Upstream commit afbd04e6 ]

Synopsys IP DWC_usb32 and DWC_usb31 version 1.90a and above deprecated
GCTL.CORESOFTRESET. The DRD mode switching flow is updated to remove the
GCTL soft reset. Add version checks to prevent using deprecated setting
in mode switching flow.
