ASoC: soc-acpi: Set mach->id field on comp_ids matches



Commit dac7cbd5 ("ASoC: Intel: soc-acpi-byt: shrink tables using
compatible IDs") and commit 959ae821 ("ASoC: Intel: soc-acpi-cht:
shrink tables using compatible IDs") simplified the match tables in
soc-acpi-intel-byt-match.c and soc-acpi-intel-cht-match.c by merging
identical entries using the new .comp_ids snd_soc_acpi_mach field to
point a single entry to multiple ACPI HIDs and clearing the previously
unique per entry .id field.

But various machine drivers from sound/soc/intel/boards rely on mach->id
in one or more ways, e.g. some drivers contain the following snippets:

	adev = acpi_dev_get_first_match_dev(mach->id, NULL, -1);

	pkg_found = snd_soc_acpi_find_package_from_hid(mach->id, ...

	if (!strncmp(snd_soc_cards[i].codec_id, mach->id, 8)) { ...

All of which are broken by the match table shrinking.

Make the snd_soc_acpi_mach.id field non const (the storage for the tables
already is non const) and on a comps_ids match copy the matching HID to
the id field to fix this.
