When parameter DWC_USB3_LPM_ERRATA_ENABLE is enabled in Andvanced
Configuration of coreConsultant, it supports of xHCI BESL Errata Dated

to send NYET response threshold based on the BESL value received in the LPM
token, and the threhold is configurable for each soc platform.

		completely, made sure threshold is only applied to
		proper core revisions. ]
