ASoC: soc-core.c: Skip dummy codec when adding platforms
When pcm_runtime is adding platform components it will scan all registered components. In case of DPCM FE/BE some DAI links will configure dummy platform. However both dummy codec and dummy platform are using "snd-soc-dummy" as component->name. Dummy codec should be skipped when adding platforms otherwise there'll be overflow and UBSAN complains.
