Alan Tull 7085e2a94f 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.

Florian Fainelli 4348f7e2ae FPGA: Add TS-7300 FPGA manager
Add support for loading bitstreams on the Altera Cyclone II FPGA
populated on the TS-7300 board. This is done through the configuration
and data registers offered through a memory interface between the EP93xx
SoC and the FPGA via an intermediate CPLD device.

The EP93xx SoC on the TS-7300 does not have direct means of configuring
the on-board FPGA other than by using the special memory mapped
interface to the CPLD. No other entity on the system can control the
FPGA bitstream.
