Ok, it looks like the FDC device should have a child device for each drive,
but my system's DSDT has none. Could we work around this in the driver by
not using _FDE/_FDI to probe unless the FDC device has at least 1 child with
an _FDI object, or should we add an entry to the quirks table for this
particular BIOS instead?
