CCW group devices are devices that use multiple subchannels on the mainframe's
channel subsystem. A qeth group device maps to subchannels and their
corresponding device numbers and device bus-IDs.
The qeth device driver requires three I/O subchannels for each HiperSockets
CHPID or OSA-Express CHPID in QDIO mode. One subchannel is for control reads,
one for control writes, and the third is for data.
The qeth device driver uses the QDIO protocol to communicate with the
HiperSockets and OSA-Express adapter.
As the node device driver is building a tree relationship between nodes the
ccwgroup device is placed besides the subchannel nodes under computer and list
the group members within a new ccwgroup capability. A new capability
ccwgroup_member is added into capability ccw to represent a device membership
to a ccwgroup. Filters are added to find ccwgroups as well as ccwgroup members.

There are some nits (e.g. formatting, proper private symbol export), but
I'll fix that before merging.

Michal,
sorry for the nits and thanks for fixing them.
