In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.
The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

`spi_transfer` + spi_transfer_delay_exec()")

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.
