Gowin. Add DHCEN primitive. (#1349)
* Gowin. Add DHCEN primitive.

This primitive allows you to dynamically turn off and turn on the
networks of high-speed clocks.

This is done tracking the routes to the sinks and if the route passes
through a special HCLK MUX (this may be the input MUX or the output MUX,
as well as the interbank MUX), then the control signal of this MUX is
used.

* Gowin. Change the DHCEN binding

Use the entire PIP instead of a wire - avoids normalisation and may also
be useful in the future when calculating clock stuff.
