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.

fpga: mgr: separate getting/locking FPGA manager
Previously when the user gets a FPGA manager, it was locked and nobody else could use it for programming.
This commit makes it straightforward to save a reference to an FPGA manager and only lock it when programming the FPGA.
Add functions that get an FPGA manager's mutex for exclusive use: * fpga_mgr_lock * fpga_mgr_unlock
The following functions no longer lock an FPGA manager's mutex: * of_fpga_mgr_get * fpga_mgr_get * fpga_mgr_put
