From: "Navare, Manasi D" <manasi.d.navare@intel.com>

These static helper functions are required to be used during
fallback link rate implemnetation so they need to be placed at the top
of the file.

v3:
* Add cleanup to other patch (Mika Kahola)
v2:
* Dont move around functions declared in intel_drv.h (Rodrigo Vivi)

Pushed this one so we don't have to keep carrying it around. Thanks for
