* gatemate: handle default parameters for IO
This is probably a VHDL specific issue. In VHDL, there is no
black-box. Primitive instantiations are done using VHDL component
instantiations and the component must have been declared with all its
ports and parameters (generic). Currently the components are
translated from cells_sim.v and cells_bb.v
If a user doesn't override a parameter, the default value is used
instead. As a consequence, nextpnr can have 'UNDEFINED' for DRIVER
or SLEW parameters of CC_IOBUF. I think this is a main difference
with verilog, where unspecified parameters do not appear.
With this change, the UNPLACED value of PIN_NAME and UNDEFINED value
of DRIVE are simply ignored.
* gatemate/pack_io.cc: also handle UNDEFINED for id_SLEW

This reverts commit c66e422dd0.
We want to guarantee minimum clock skew, so we need pip delay.
