This is a workaround for STAR 4846132, which only affects DWC_usb31 version2.00a operating in host mode.

There is a problem in DWC_usb31 version 2.00a operating in host mode that would cause a CSR read timeout When CSR read coincides with RAM Clock Gating Entry. By disable Clock Gating, sacrificing power consumption for normal operation.

What commit id does this fix? How far back should it be backported in the stable releases?
