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.
