ALSA/hda: intel-dsp-config: reduce log verbosity

The information on PCI class/subclass was interesting in the Skylake
timeframe, since the DSP was only enabled on a limited number of
platforms. Now most Intel platforms do enable the DSP, so the
information is less interesting to log.

When a DSP driver is used, the common helper may be called multiple
times due to deferred probes, but there's no reason to print the same
information multiple times. Using dev_info_once() covers all the
existing usages for internal cards with DSPs. External cards don't
rely on DSPs so far.
