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
