Support multiple headphone drivers in same machine driver. In this
case, both rt5682 and rt5682s are supported and enumerated by different
ACPI HID "10EC5682" and "RTL5682".
V2 Changes:
- remove useless 'NULL', 'false' in if-condition
- can use 'comp_ids' field alone to enumerate driver
- add comma to the end of entry in structure initialization
- keep the table of byt/cht/cml/icl untouched

2.25.1
A machine driver needs to be enumerated by more than one ACPI HID if
it supports second headphone driver (i.e. rt5682 and rt5682s).
However, the id field in snd_soc_acpi_mach structure could contain
only one HID. By adding a 'comp_ids' field which can contain several
HIDs, we can enumerate a machine driver by multiple ACPI HIDs.

In cover letter you mention:
"- can use 'comp_ids' field alone to enumerate driver"
which leads me to an opinion that field 'id' should be removed,
entirely. With 'comp_ids' added, 'id' is basically rendered
optional/redundant.

Such loops are hard to maintain i.e. 'comp_ids' acts here like a flex
array that follows 'id'. Removal of 'id' field and streamlining code to
only use 'comp_ids' should make this loop more intuitive.

Well, we could have mentioned files updated in the follow up patches
i.e. treat this patch as a 'preparation step'. In the long run, having
two places for id initialization will cost us more than updating all
those files.
Have no problem with leaving current patch as is if the end goal is
removal of 'id' field. In some future series I guess..

Changing all the tables adds more noise IMHO. There are 15 files and
about 100 ids.
This patch provides an opportunity to reduce duplication, that's good,
but let's leave all the existing unique table entries alone, shall we?
