ASoC: extra format on each DAI

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Current clock provider/consumer setting is set by dai_link->dai_fmt, and it
is Codec base on Sound Card driver (= SND_SOC_DAIFMT_CBx_CFx).

Current CPU/Codec drivers are already based on its own base
(= SND_SOC_DAIFMT_Bx_Fx). So, Codec clock setting uses dai_link->dai_fmt
as-is, and CPU side clock setting is created from Codec base setting by
flipping. Because of this, we can't set both CPU/Codec clock consumer for
example.

To solve this issue, this patch-set adds new ext_fmt on each DAI.
It can keep compatible with legacy style.

	1. SND_SOC_DAIFMT_FORMAT_MASK
	2. SND_SOC_DAIFMT_CLOCK
	3. SND_SOC_DAIFMT_INV
	4. SND_SOC_DAIFMT_CLOCK_PROVIDER

	dai_fmt : dai_link->dai_fmt = common settings
	ext_fmt : each DAI settings

Legacy
	dai_fmt  includes 1, 2, 3, 4

New style
	dai_fmt  includes 1, 2, 3
	ext_fmt  includes 4

Audio-Graph-Card2 will use this new style by this patch-set.
By this patch, Card2 default behavior (= no "clock-master / frame-master"
settings on DT) will be changed, but no drivers are using it.

In case of no DAI has "clock-master / frame-master" property on DT,
it will be...

Legacy
	CPU  : provider (because flipped from Codec)
	Codec: consumer

New style
	CPU  : consumer
	Codec: consumer

One note is that Simple-Card, Audio-Graph-Card don't implement
this new style to keep compatiblily.

In Overlay case, port order can be random, so we shouldn't use get_next()
function to get next port.
