--warn-no-port directives in pins.pcf ineffective


#1

The --warn-no-port directives in the pins.pcf file in the templates and examples are ineffective in the latest version of arachne-pnr, and so builds give lots of warning messages. I believe they should be changed to -nowarn - see https://forum.mystorm.uk/t/syntax-of-pcf-file/383/5.

The change works for me.
