b02a40713d 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

e150e3f4ad 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.

5ebae801d9 fpga: dfl: fme-mgr: add compat_id support 
This patch adds compat_id support to fme manager driver, it
reads the ID from the hardware register. And it could be used
for compatibility check before partial reconfiguration.
