Portals are memory mapped interfaces to QMan that allow low-latency, lock-less
interaction by software running on processor cores, accelerators and network
interfaces with the QMan

The hardware index of the channel. This can also be
determined by dividing any of the channel's 8 work queue
IDs by 8
In addition to these properties the qman-portals should have sub-nodes to
represent the HW devices/portals that are connected to the software portal
described here
required:

- reg
- interrupts
