"ACPI0004","PNP0A05" and "PNP0A06" are all defined in array
container_device_ids[], so use it, but not the hard coding style.
Also, introduce a new api is_container_device() to determine if a
device is a container device.
change log v2 -> v3:
1. change the is_container_device()'s return value type from int to bool.
