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.
