ASoC: makes CPU/Codec channel connection map more generic
Current ASoC CPU:Codec = N:M connection is using connection mapping idea,
but it is used for N < M case only. We want to use it for any case.
By this patch, not only N:M connection, but all existing connection
(1:1, 1:N, N:N) will use same connection mapping. Then, because it will
use default mapping, no conversion patch is needed to exising drivers.
More over, CPU:Codec = N:M (N > M) also supported in the same time.
ch_maps array will has CPU/Codec index by this patch.

ch_map[1].cpu = 1 ch_map[1].codec = 1
ch_map[2].cpu = 2 ch_map[2].codec = 1
