hatch_fp: Switch to UNUSED pins mechanism
This CL enables UNUSED pins for hatch_fp.
This places the unused/unconnected pins in the
lowest power state.
Using the UNUSED pins mechanism should be functionally
equivalent to the previous method of declaring these pins
as analog inputs.
See crrev.com/c/1894242 for implementation details.
