ASoC: intel: add function stub when ACPI is not enabled
Add function stub for "sst_acpi_find_name_from_hid()"
when CONFIG_ACPI is not enabled so that the driver will build
successfully. This fixes the following build errors:
(loadable module)
ERROR: "sst_acpi_find_name_from_hid" [sound/soc/intel/boards/snd-soc-sst-bytcr-rt5640.ko] undefined!
(or built-in)
bytcr_rt5640.c:(.text+0x26fc52): undefined reference to `sst_acpi_find_name_from_hid'
