ACPI: Check for any matching CID when walking namespace. 

The callback function acpi_ns_get_device_callback called from
acpi_get_devices() will check CID's if the HID does not match.  This code
has a bug where it requires that all CIDs match the HID. Changed the code
so that any CID match will do.
