ASoC: SOF: Intel: hda-ctrl: add missing WAKE_STS clear

Browse source

For some reason, the programming sequences in the SOF driver do not
include a clear of the WAKE_STS bits before resetting the controller.

This clear is not formally required by the HDaudio specification, but
was added to harden the snd-hda-reset back in 2007. Adding this
sequence back avoids an issue reported by the Intel CI.
