ASoC: Intel: sof_sdw: Move get_codec_dai_by_name() into sof_sdw itself

Currently sof_sdw relies on sof_board_helpers to provide
get_codec_dai_by_name(), but that is the only function from
sof_board_helpers it uses and no other machine driver requires
that function. There is no reason for sof_sdw to select SSP_COMMON
but more and more functions in sof_board_helpers are gaining
dependencies on functions that would require stubs for sof_sdw to
build without it.  Firstly it was sof_ssp_get_codec_name(), as was
fixed in commit c1469c3a8a30 ("ASoC: Intel: ssp-common: Add stub for
sof_ssp_get_codec_name"), now it is:

ERROR: modpost: "sof_ssp_detect_amp_type"
[sound/soc/intel/boards/snd-soc-intel-sof-board-helpers.ko] undefined!
ERROR: modpost: "sof_ssp_detect_codec_type"
[sound/soc/intel/boards/snd-soc-intel-sof-board-helpers.ko] undefined!

Rather than adding more stubs, simply move the affected function
to the sof_sdw machine driver itself and no longer select
SND_SOC_INTEL_SOF_BOARD_HELPERS at all. This should allow work on
SSP_COMMON to progress without affecting sof_sdw.
