acpi_evaluate_dsm_typed function needs to be gaurded with CONFIG_ACPI to
avoid redefintion error when stub is also enabled.

In file included from ../drivers/bluetooth/btintel.c:13:
../include/acpi/acpi_bus.h:57:1: error: redefinition of 'acpi_evaluate_dsm_typed'
   57 | acpi_evaluate_dsm_typed(acpi_handle handle, const guid_t *guid,..
      | ^~~~~~~~~~~~~~~~~~~~~~~
In file included from ../drivers/bluetooth/btintel.c:12:
../include/linux/acpi.h:967:34: note: previous definition of
'acpi_evaluate_dsm_typed' with type 'union acpi_object *(void *,
const guid_t *, u64,  u64,  union acpi_object *, acpi_object_type)'
{aka 'union acpi_object *(void *, const guid_t *, long long unsigned int,
long long unsigned int,  union acpi_object *, unsigned int)'}
  967 | static inline union acpi_object
*acpi_evaluate_dsm_typed(acpi_handle handle,

Fixes: 1b94ad7ccc21 ("ACPI: utils: Add acpi_evaluate_dsm_typed() and acpi_check_dsm() stubs")
