David Shah 4bc68c9620 Fix icebox_vlog for up5k 
Since ce1d811, SHIFTREG_DIV_MODE is now 2 bits for the up5k

Sylvain Munaut ce1d811d21 icebox: Add support for the bit 1 of SHIFTREG_DIV_MODE on UP5k 
This allows selection of the div-by-5 mode of the PLL.
This bit can't be fuzzed because it's not supported by the lattice
tools at all ...

This only works for sure on the UP5k.

I tested HX8k and it didn't support it, so I'm only adding this on
the known working FPGA.

Previously if you were doing;

```

```

Now you get;
```

  File "icebox_vlog.py", line 948, in <module>
    assert False, "\n  ".join(emsg)
AssertionError: Single-driver-check failed for 2 nets:

Tim 'mithro' Ansell 82f2f3d278 HLC: Use '~>' instead of '<->' for routing switches. 
As mentioned in ca6b2d9ebd, the 'routing'
switches are not actually bidirectional. This makes the '<->' specifier
very misleading.

Instead use '~>' to differentiate it from the 'buffer' switches.
