Add devm_fpga_mgr_create() which is the managed
version of fpga_mgr_create().
Change current FPGA manager drivers to use
devm_fpga_mgr_create()

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.

This interface was designed for streaming, but write_init's buf
argument has an unclear purpose. Define it to be the first bytes
of the bitstream. Each driver gets to set how many bytes (at most)
it wants to see. Short bitstreams will be passed through as-is, while
long ones will be truncated.
The intent is to allow drivers to peek at the header before the transfer
actually starts.
