[PATCH 4/7] ASoC: SOF: pci: move DSP_CONFIG use to platform-specific drivers

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

There is no reason why we should call the intel_dspcfg helpers from
common code, this should be moved in Intel-specific code and only
called from platforms where a conflict may occur with the HDaudio or
SST/Skylake driver.
