ASoC: soc-core: Enable to use extra format on each DAI
Current ASoC is using dai_link->dai_fmt to set DAI format for both
CPU/Codec. But because it is using same settings, and
SND_SOC_DAIFMT_CLOCK_PROVIDER is flipped for CPU, we can't set both
CPU/Codec as clock consumer, for example.
To solve this issue, this patch enable to use extra format for each
DAI which can keep compatibility with legacy system,
1. SND_SOC_DAIFMT_FORMAT_MASK
2. SND_SOC_DAIFMT_CLOCK
3. SND_SOC_DAIFMT_INV
4. SND_SOC_DAIFMT_CLOCK_PROVIDER
Legacy
dai_fmt includes 1, 2, 3, 4
New idea
dai_fmt includes 1, 2, 3
ext_fmt includes 4
