Add authenticate-fpga-config property for FPGA bitstream authentication,
which makes sure a signed bitstream has valid signatures.

v4: explain authenticate-fpga-config flag further
v3: no change
v2: put authenticate-fpga-config above partial-fpga-config

Maybe I would highlight two things:
a) If you add 'authenticate-fpga-config' you are not allowed to add new
nodes
b) If you add 'authenticate-fpga-config' you are not alllowed to add
other operations
Regards,- partial-fpga-config : boolean, set if partial reconfiguration is to be done,Thanks,
otherwise full reconfiguration is done.
- external-fpga-config : boolean, set if the FPGA has already been configured
