ASoC: sdw_utils: cs_amp: Delete bogus and incorrect capture channel fixup

Delete the asoc_sdw_cs_spk_feedback_rtd_init(). This is not needed now
that the ASoC bug it was working around has been fixed. And it was broken
anyway because it didn't match the way the core SoundWire code mapped
codec channels to frame bitslots.

This code was added to avoid a problem where multiple codec DP outputs
were mapped to the same SoundWire frame bit slot. This would allow a
user to break the SoundWire bus just by enabling mixer outputs using
ALSA controls.

As no production system has used the capture stream, this workaround
was of little consequence and the problem of conflicting DP mappings
was not investigated.

The ASoC bug that enabled too many channels on each codec has now been
fixed. So this workaround can be completely deleted.
