Driver has IO wrappers but xlnx_pr_decouple_read() is not used and readl is
used instead which is just wrong.
It is also generating sparse issue that xlnx_pr_decouple_read() is unused.

The FPGA bridge 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 and combines the create() and register()
functions into a single register() function.

This patch adds support for Xilinx Dynamic Function eXchange(DFX) AXI
shutdown manager IP. It can be used to safely handling the AXI traffic
on a Reconfigurable Partition when it is undergoing dynamic reconfiguration
and there by preventing system deadlock that may occur if AXI transactions
are interrupted during reconfiguration.
PR-Decoupler and AXI shutdown manager are completely different IPs.
But both the IP registers are compatible and also both belong to the
same sub-system (fpga-bridge).So using same driver for both IP's.

In probe, the driver checks for devm_clk_get return and print error
message in the failing case. However for -EPROBE_DEFER this message
is confusing so avoid it.

Change fpga_bridge_register to not set drvdata. This is to support
the case where a PCIe device can have more than one bridge.
Add API functions to create/free the fpga bridge struct. Change
fpga_bridge_register/unregister to take FPGA bridge struct as
the only parameter.
struct fpga_bridge
*fpga_bridge_create(struct device *dev, const char *name,
const struct fpga_bridge_ops *br_ops,
void *priv);
void fpga_bridge_free(struct fpga_bridge *br);
int fpga_bridge_register(struct fpga_bridge *br);
void fpga_bridge_unregister(struct fpga_bridge *br);
Update the drivers that call fpga_bridge_register with the new API.
