Gowin. Renaming inputs of the DCS primitive.

Browse source 
The dynamic clock selection (DCS) primitive has undergone changes with
the release of the GW5A series—the CLK0,1,2,3 inputs are now
CLKIN0,1,2,3, but only for GW5A series chips.

There are no functional changes, only renaming.

Here we are transferring the description of the DCS primitive from
general to specialized files for each chip series.

We have also fixed a bug in the generation script that caused the loss
of primitive parameters. Fortunately, this only affected the
analog-to-digital converter, which has not yet been implemented.
