util_upack: util_upack_hw.tcl: Disable unused interfaces instead of not creating them 

Currently the util_upack_hw.tcl script does not create interfaces if they
are not used in the current configuration. This has the disadvantage that
the ports belonging to these interfaces are not included in the generated
HDL wrapper. Which will generate a fair bunch of warnings when synthesizing
the HDL.

Instead always generate all interfaces, but disable those that are not used
in the current configuration. This will make sure that the ports belonging
to these interfaces are properly tied-off in the generate wrapper HDL.

This reduces the amount of false positive warnings generated and makes it
easier to spot actual issues.
