Remove the errata workaround from soc specific file for LS2080
The commit message does not explain why this change is legal or needed.
This errata a008751 is applied on Soc specific file currently. We are moving this errata to a a file where all the errata implementation will take Place for usb for fsl. Implementation of the errata will follow in Patch 5/5.
However, I cannot reference to the driver specific implementation till it is committed. So, this is just the description of removing the errata from soc specific file.
