Add dedicated structure with power cable setting for Mellanox system from
family msn21xx. These systems do not have physical device for power
unit controller. So, in case power cable is inserted or removed, relevant
interrupt signal is to be handled, status will be updated, but no device
is to be associated with this signal.
Add definition for interrupt low aggregation signal. On system from
msn21xx family, low aggregation mask should be removed in order to allow
signal hit CPU.
