    Chris Packham authored
    Workaround makes FS as default mode on all affected socs.
    Add support to check erratum-A005275 validity for an soc. This info is
    required to determine whether a given soc is affected by this erratum.
    Add quirk for this erratum "has_fsl_erratum_a005275" . This quirk is used
    to enable workaround for the errata
    Force FS mode as default by:
            - making EPS as FS
            - setting PFSC bit to disable HS chirping
    This workaround can be disabled by mentioning "no_erratum_a005275" in
    hwconfig string
