peci: Extend peci client with Domain ID information
Since PECI Target addressing has been changed to use Domain ID
information, each peci_client instance should correspond with both CPU
ID and Domain ID.
Let's extend peci_client structure, sysfs API and intel-peci-client to
use Domain ID. Make MFD device ID as a combination of peci adapter
number, CPU ID and Domain ID.
