Add devm_fpga_region_create() which is the
managed version of fpga_region_create().
Change current region drivers to use
devm_fpga_region_create().

This patch introduces a compat_id pointer member and sysfs interface
for each fpga region, similar as compat_id for fpga manager, it allows
applications to read the per region compat_id for compatibility
checking before other actions on this fpga-region (e.g. PR).

Add fpga_region_create/free API functions.
Change fpga_region_register to take FPGA region struct as the only
parameter. Change fpga_region_unregister to return void.
struct fpga_region *fpga_region_create(struct device *dev,
struct fpga_manager *mgr,
int (*get_bridges)(struct fpga_region *));
void fpga_region_free(struct fpga_region *region);
int fpga_region_register(struct fpga_region *region);
void fpga_region_unregister(struct fpga_region *region);
Remove groups storage from struct fpga_region, it's not
needed. Callers can just "region->dev.groups = groups;"
after calling fpga_region_create.
Update the drivers that call fpga_region_register with the new API.

Make it easy to add attributes to low level FPGA drivers the right
way. Add attribute groups pointers to structures that are used when
registering a manager, bridge, or group. When the low level driver
registers, set the device attribute group. The attributes are
created in device_add.

Add a function for searching the fpga-region class. This
will be useful when device tree code is no longer in the
same file that declares the fpga-region class. Another
step in separating common FPGA region code from device
tree support.

Another step in separating common code from device tree specific
code for FPGA regions.
* add FPGA region register/unregister functions.
* add the register/unregister functions to the header
* use devm_kzalloc to alloc the region.
* add a method for getting bridges to the region struct
* add priv to the region struct
* use region->info in of_fpga_region_get_bridges

* Create fpga-region.h.
* Export fpga_region_program_fpga.
* Move struct fpga_region and other things to the header.
This is a step in separating FPGA region common code
from Device Tree support.
