On some platforms, ACPI _DSM method (nouveau_op_dsm_muid, function 0)Tested-by: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxx>
has special requirements on the fourth parameter, which is different
from ACPI specifications. So revert to the private implementation
to check availability of _DSM functions instead of using common
acpi_check_dsm() interface.
