Subject: [PATCH v8 5/5] usb :fsl: Change string format for errata property

From: Nikhil Badola <nikhil.badola@...escale.com>

Remove USB errata checking code from driver. Applicability of erratum
is retrieved by reading corresponding property in device tree.
This property is written during device tree fixup.
