[PATCH 1/3] ASoC: amd: acp: add ACPI dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

A newly added function requires CONFIG_ACPI to avoid a build error:

sound/soc/amd/acp/acp-legacy-common.c: In function 'check_acp_pdm':
sound/soc/amd/acp/acp-legacy-common.c:401:19: error: implicit declaration of function 'acpi_find_child_device'; did you mean 'acpi_match_device'? [-Werror=implicit-function-declaration]
  401 |         pdm_dev = acpi_find_child_device(ACPI_COMPANION(&pci->dev), pdm_addr, 0);
      |                   ^~~~~~~~~~~~~~~~~~~~~~
      |                   acpi_match_device

The acp drivers really only work when ACPI is enabled already, so just
avoid the build failure with hard dependency in everything that
enables the acp-legacy-common portion.

Fixes: 3a94c8ad0aae ("ASoC: amd: acp: add code for scanning acp pdm controller")
