fpga: manager: change api, don't use drvdata
Change fpga_mgr_register to not set or use drvdata. This supports
the case where a PCIe device has more than one manager.
Add fpga_mgr_create/free functions. Change fpga_mgr_register and
fpga_mgr_unregister functions to take the mgr struct as their only
parameter.
struct fpga_manager *fpga_mgr_create(struct device *dev,
const char *name,
const struct fpga_manager_ops *mops,
void *priv);
void fpga_mgr_free(struct fpga_manager *mgr);
int fpga_mgr_register(struct fpga_manager *mgr);
void fpga_mgr_unregister(struct fpga_manager *mgr);
Update the drivers that call fpga_mgr_register with the new API.
