fpga: region: change api, add fpga_region_create/free
Add fpga_region_create/free API functions. Change fpga_region_register to take FPGA region struct as the only parameter. Change fpga_region_unregister to return void. struct fpga_region *fpga_region_create(struct device *dev, struct fpga_manager *mgr, int (*get_bridges)(struct fpga_region *)); void fpga_region_free(struct fpga_region *region); int fpga_region_register(struct fpga_region *region); void fpga_region_unregister(struct fpga_region *region); Remove groups storage from struct fpga_region, it's not needed. Callers can just "region->dev.groups = groups;" after calling fpga_region_create. Update the drivers that call fpga_region_register with the new API.
