Make it easy to add device attribute groups when registering an FPGA
manager, bridge, or region.  This way, the sysfs attributes are added
in device_add instead of afterwards which can lead to race
conditions [1].

Patch 1: add groups to the structs that are used when a manager, bridge,
or region is registered.

Patch 2: changes to altera cvp FPGA manager to use this method of
registering.

I've tested this method on platform devices.  Patch 2 builds but is
untested.

This patchset is dependent on my "non-dt support" patchset currently
under review.
