ACPI: fix a regression of ACPI device driver autoloading
commit 3620f2f2f39e7870cf1a4fb2e34063a142f28716 sets the cid of
ACPI video/dock/bay device and leaves the hid empty.
As a result, "modalias" should export the cid for
devices which don't have a hid.
ACPI Video driver is not autoloaded with
commit 3620f2f2f39e7870cf1a4fb2e34063a142f28716 applied.
