fpga: mgr: Use standard dev_release for class driver

The FPGA manager 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 for the freeing of the class data structure
and combines the create() and register() functions into a single
register() or register_full() function.

The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.

The devm_fpga_mgr_register() function is retained, and the
devm_fpga_mgr_register_full() function is added.

fpga: fpga-mgr: wrap the state() op

An FPGA manager should not be required to provide a state() op.
Add a wrapper consistent with the other op wrappers.
Move op check to wrapper.
Default to FPGA_MGR_STATE_UNKNOWN, what noop state() ops use.
Remove unneeded noop state() ops

fpga: dfl-fme-mgr: fix FME_PR_INTFC_ID register address.

FME_PR_INTFC_ID is used as compat_id for fpga manager and region,
but high 64 bits and low 64 bits of the compat_id are swapped by
mistake. This patch fixes this problem by fixing register address.
