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
