[RFC PATCH 26/57] drivers: acpi: Clean up acpi_dev_match_cb

acpi_dev_match_cb match function modifies the "data" argument
to pass on a result which could be easily deduced from the result
of the bus_find_device() call at the caller site. Clean this
up in preparation to convert the "match" argument for bus_find_device.
