[reggen] Rewrite param value from the script
Now reggen.validate.validate function accepts positional argument, which
overwrites the default value of `param` in `param_list`.
This can let the tool creates multiple RTLs from a single hjson.
To do that, regtool.py also has `param` argument now. The format is
--param ParamA:ValueA ParamB:ValueB. You need to add the param argument
at the end of the script (after input path).
This is related to #30 #47
