DQCE and DCS primitives are added - disabling the clock in a quadrant and dynamically selecting the clock source accordingly. With this commit we are finally able to use clock lines 6 and 7 :) Added examples for Tangnano1k, Tangnano4k, Tangnano9k, Primer20k, Tangnano20k boards. From the internals: in addition to the well-known fuse tables SHORTVAL and LONGVAL, functions have been added for working with another table - LONGFUSE. It differs in that it describes the fuses of primitives with only one parameter, in contrast to two parameters for SHORTVAL and 16 parameters for LONGVAL. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

Until the PR goes through in nextpnr, there will be errors, so we'll wait. |

Well, for some time only one version of the examples will be green - until the release of yosys, since there are our changes in main. |

well we're in luck there was a release 3 days ago |

Great! Now we have 2 green pieces again :) |
