Well this is pretty disappointing

This is clearly built upon my commit [1] (which itself is built upon QC
downstream, for which it retains the QuIC copyright), which can be seen
e.g. in the funny bitwise ORing in wcd937x_set_micbias_data or the
precise comments/function ordering..

Please at least include the Linaro copyright.
