Hi Mark

These are v2 of parsing for daifmt.

I want to add new audio-graph-card2 sound card driver,
and this is last part of necessary soc-core cleanup for it.

Current some drivers are using DT, and then,
snd_soc_of_parse_daifmt() parses daifmt, but bitclock/frame provider
parsing part is one of headache, because we are assuming below both cases.

A)	node {
		bitclock-master;
		frame-master;
		...
	};

B)	link {
		bitclock-master = <&xxx>;
		frame-master = <&xxx>;
		...
	};

The original was style A), and style B) was added later.

snd_soc_of_parse_daifmt() parses A) style as original style,
and user need to update to B) style for clock_provider part if needed.

To handle it more flexibile, this patch-set adds new functions
which separates snd_soc_of_parse_daifmt() helper function.

	snd_soc_daifmt_parse_format()			: format part
	snd_soc_daifmt_parse_clock_provider_as_flag()	: clock part for style A)
	snd_soc_daifmt_parse_clock_provider_as_phandl()	: clock part for style B)
	snd_soc_daifmt_parse_clock_provider_as_bitmap()	: clock part use with _from_bitmap

v1 -> v2
	- tidyup parse_clock_provider functions to _as_flag/phandle/bitmap()
	- don't exchange code style on each drivers.
