device-manager: Add 'role' parameter to device_list_get_device()

With new role parameter is specified, it returns a device considering
the role. For this, pa_tz_device_get_role() is added to tizen-device.c.

It is revised not to judge whether a device type is for multi-devices
by predefined device types. So, device_type_is_avail_multi_device() is
removed from tizen-device-def.c.
