Fix the "comparison with less than zero" warning reported by
cppcheck for the unsigned (size_t) parameter count of the
alt_pr_fpga_write() function.

The FPGA manager class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes
the managed resource code for the freeing of the class data structure
and combines the create() and register() functions into a single
register() or register_full() function.
The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.
The devm_fpga_mgr_register() function is retained, and the
devm_fpga_mgr_register_full() function is added.

Make alt_pr_unregister function void, since it always returns 0,
and nothing would act on the value anyways.

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.
