drm/nouveau/acpi: ensure matching ACPI handle and supported functions

Ensure that the returned set of supported DSM functions (MUX, Optimus)
match the ACPI handle that is set in nouveau_dsm_pci_probe.

As there are no machines with a MUX function on just one PCI device and
an Optimus on another, there should not be a functional impact. This
change however makes this implicit assumption more obvious.

Convert int to bool and rename has_dsm to has_mux while at it. Let the
caller set nouveau_dsm_priv.dhandle as needed.

 v2: pass dhandle to the caller.
