simple_card_utils was created as simple_card_core in 1st prototype,
and current code still have it. Let's tidyup

Remove cpu/codec pointer check from asoc_simple_card_canonicalize_dailink()
This is verbose check, and will be issue if CPU name was created by
fmt_single_name() on simple-scu-card.c.
see also asoc_simple_card_canonicalize_cpu()

simple-card-utils might be used as module, but MODULE_xxx()
information was missed. This patch adds it.
Otherwise, we will have below error, and can't use it.

Current simple-card is creating dai_link->name / dai_link->stream_name.
These are based on CPU + Codec name, or "fe.CPU" or "be.Codec" if it
was DPCM.
This patch adds asoc_simple_card_set_dailink_name() and set dailink
name as common method.

Current ALSA SoC has simple-card driver which is supporting both
platform and DT probe.
Now, some sound cards driver are created based on simple-card.
They have similar feature or function, but implemented separately
on each drivers. This is a waste of code.
OTOH, merging these driver into same driver is highly risk,
because it will be very difficult to keep compatibility.
More over, ALSA SoC want to have graph base of DT feature in the
future. Maybe it want to use simple-card like feature / function.
Because of these background, this patch creates simple-card
helper utils, and provides common function to each drivers.
1st is asoc_simple_card_parse_daifmt()
