  1. Bulk port of all gateware to nMigen compatibility layer.

  2. gateware.analyzer: adjust for nMigen. 

    There were three issues:
  * nMigen SyncFIFOBuffered no longer provides access to the inner
    FIFO. Therefore, level of the outer FIFO is used instead.
  * nMigen simulator no longer allows setting Signals that are not
    actually used anywhere in simulation.
  * In nMigen, FIFOInterface.read() is 1-cycle, not 2-cycle.
    This requires adjustment of our read loop (which would ideally
    be rewritten.)

  3. gateware.pads: adjust for nMigen. 

    nMigen provides a native replacement for what Pads was trying to do,
so this module is essentially deprecated, and no particular care has
been taken to keep it in good shape.

  4. gateware.pll: adjust for nMigen. 

    This doesn't include adjustments for gateware.platform. Fortunately,
only a few applets use PLL, so this can be done later.

  6. gateware.fx2_crossbar: adjust for nMigen. 

    nMigen now provides XDR in the platform layer, so it is no longer
necessary to instantiate SB_IO.

  9. access.direct.multiplexer: adjust for nMigen. 

    nMigen build plans contain all files, including the constraint files,
so it is no longer necessary to track IO placement in attributes.
