UPSTREAM: usb: dwc3: core: Workaround for CSR read timeout

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.
