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.
