845089bbf5 fpga: add attribute groups
Make it easy to add attributes to low level FPGA drivers the right
way.  Add attribute groups pointers to structures that are used when
registering a manager, bridge, or group.  When the low level driver
registers, set the device attribute group.  The attributes are
created in device_add.

503d4b7a44 fpga: region: add fpga_region_class_find
Add a function for searching the fpga-region class.  This
will be useful when device tree code is no longer in the
same file that declares the fpga-region class.  Another
step in separating common FPGA region code from device
tree support.

52a3a7ccce fpga: region: add register/unregister functions
Another step in separating common code from device tree specific
code for FPGA regions.

* add FPGA region register/unregister functions.
* add the register/unregister functions to the header
* use devm_kzalloc to alloc the region.
* add a method for getting bridges to the region struct
* add priv to the region struct
* use region->info in of_fpga_region_get_bridges

59460a9305 fpga: region: add fpga-region.h header
* Create fpga-region.h.
* Export fpga_region_program_fpga.
* Move struct fpga_region and other things to the header.

This is a step in separating FPGA region common code
from Device Tree support.
