ASoC: amd: Add ACPI dependency to fix build error

As reported by the kernel test robot, the following error occurs:

sound/soc/amd/yc/acp6x-mach.c: In function 'acp6x_probe':
>> sound/soc/amd/yc/acp6x-mach.c:573:15: error: implicit declaration of function 'acpi_evaluate_integer'; did you mean 'acpi_evaluate_object'? [-Werror=implicit-function-declaration]
573 | ret = acpi_evaluate_integer(handle, "_WOV", NULL, &dmic_status);
| ^~~~~~~~~~~~~~~~~~~~~
| acpi_evaluate_object
cc1: some warnings being treated as errors

The function 'acpi_evaluate_integer' and its prototype in 'acpi_bus.h'
are only available when 'CONFIG_ACPI' is enabled. Add a 'depends on ACPI'
directive in Kconfig to ensure proper compilation.
