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.
