Sylvain Munaut 6cb4e2e83b ice40/pack: During IO packing, remove any unused input connection ...

This is mostly for the benefit of PLL placement because the D_IN_x
ports are used for other purposes when PLL is enabled so we need to
make sure nothing is connected there already. (even an unused net is
too much)
