  1. vendor: use nextpnr -12k for -12F devices; remove theoretical devices 

    nextpnr now supports -12k; which replaces the use of -25k and --idcode
together to build bitstreams compatible with -12F devices. Use this.

This also removes the LFEUM-12K and its 5G counterpart; as per Dave Shah
they're currently only theoretical FPGAs.
