add to dahdi_device a "hardware_id" attribute as an alternative to "location"
- The "hardware_id" does not change with device location (e.g: when a PCI
card is moved from one slot to another).
- Not all devices have this attribute. It is legal for it to be NULL (that
is the default for all low-level drivers that do not set it explicitly).
- When "hardware_id" is NULL, the sysfs attribute value is "\n"
