ASoC: dt-bindings: audio-graph-port: Add dai-tdm-slot-width-map
...
Some audio hardware cannot support a fixed slot width for all sample
widths, or a slot width equal to the sample width for all sample widths.
This is usually due either to limitations of the audio serial port or
system clocking restrictions.
This property allows setting a mapping of sample widths and the
corresponding tdm slot widths. The slot count is also provided for
each slot width - although this would almost always be the same for
all slot widths this allows for possibly adding extra padding slots
to maintain a fixed bitclock frequency.

ASoC: dt-bindings: audio-graph-port: enable both flag/phandle for bitclock/frame-master
...
snd_soc_daifmt_parse_clock_provider_raw() is handling both
bitclock/frame-master, and is supporting both flag/phandle.
Current DT is assuming it is flag style.
This patch allows both case.

Now that we have an OF graph schema, let's use it for the
audio-graph-port schema.

ASoC: dt-bindings: Move port/ports properties out of audio-graph-port.yaml
...
Users of the audio-graph-port schema need to define how many ports
and what each port is, so they need to define 'ports' and/or 'port'
anyways. Let's drop 'ports' and 'port' from the schema and adjust users
to reference audio-graph-port.yaml from a port property.

An endpoint is not a device and it is recommended to use clocks property
in the device node. Hence reverting the original change.

Add optional 'clocks' property to audio port 'endpoint' node. One

ASoC: audio-graph-card: Drop remote-endpoint as required property
...
The remote-endpoint may not be available if it is part of some
pluggable module. One such example would be an audio card, the
Codec endpoint will not be available until it is plugged in.
Hence drop 'remote-endpoint' as a required property.

ASoC: audio-graph-card: Refactor schema
...
There can be customized sound cards which are based on generic audio
graph. In such cases most of the stuff is reused from generic audio
graph. To facilitate this, refactor audio graph schema into multiple
files and the base schema can be reused for specific sound cards.
The graph card nodes and port nodes are separate entities, so they
should be separate schemas.
