ASoC: soc.h: remove num_cpus/codecs

Current rtd has both dai_link pointer (A) and num_cpus/codecs (B).

(A)	rtd->dai_link	= dai_link;
(B)	rtd->num_cpus	= dai_link->num_cpus;
(B)	rtd->num_codecs	= dai_link->num_codecs;

But, we can get num_cpus/codecs (B) via dai_link (A).
This means we don't need to keep num_cpus/codecs on rtd.
This patch removes these.
