41c80be24b s390/net: move pnet constants 
There is no need to define these PNETID related constants in
the pnet.h file, since they are just used locally within pnet.c.
Just code cleanup, no functional change.

b6ef86e962 s390/net: add pnetid support 
s390 hardware supports the definition of a so-call Physical NETwork
IDentifier (short PNETID) per network device port. These PNETIDS
can be used to identify network devices that are attached to the same
physical network (broadcast domain).

This patch provides the interface to extract the PNETID of a port of
a device attached to the ccw-bus or pci-bus.

Parts of this patch are based on an initial implementation by
Thomas Richter.
