ACPI: remove acpi_device.flags.hardware_id
Every acpi_device has at least one ID (if there's no _HID or _CID, we give it a synthetic or default ID). So there's no longer a need to check whether an ID exists; we can just use it. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
