acpi_dev_get_first_match_dev() searches for an acpi_handle
instantiated by the ACPI table scanning done early during boot.

Two of three machine drivers using this search don't deal with errors
and the one which does (bytcr_rt5651) returns -ENODEV, which doesn't
make sense here: an alternate driver will not be probed.

Add consistent error handling and report -ENXIO.
