PATCH v4 1/1 ASoC: Intel - Convert to use acpi_dev_get_first_match_name()

Instead of home grown snd_soc_acpi_find_name_from_hid() use acpi_dev_get_first_match_name().

Tested-by Pierre-Louis Bossart <[email protected]>

- rebase on top of topic/intel branch of ASoC tree;

The patch has dependency on Pierre's
"ASoC: Intel: bytcht_es8316: fix HID handling" submitted earlier and pushed AFAICS to sound.git/topic/intel.
