[PATCH v1 0/3] fpga: Use standard class dev_release function

[Russ Weight]

The FPGA framework has a convention of using managed resource
functions to allow parent drivers to manage the data structures
allocated by the class drivers. They use an empty *_dev_release()
function to satisfy the class driver.

This is inconsistent with linux driver model.

These changes remove the managed resource functions and populate
the class dev_release callback functions. They also merge the
create and register functions into a single register function for
each of the fpga-mgr, fpga-region, and fpga-bridge class drivers.

For more context, refer to this email thread:

I turned on the configs assocated with each of the modified files,
but I must have been missing some dependencies, because not all
of them compiled. I did a run-time test specifically with the
dfl-fme infrastructure. This would have exercised the region,
bridge, and fpga-mgr frameworks.
