software/ors-amarisoft: enb: Try to support NR/FDD a bit

It should be already generally supported, but many parameters needs in NR case
are currently hardcoded to their TDD values. I've adjusted only a few of them
and stopped, becuase there is currently no practical case at hand for me to
test it. Still I think it makes sense to save this first step.

For ORS, who uses TDD, rendered config stays practically the same:

```
$ ./pythonwitheggs slapos-render-config.py && xdiff -C -C config/{old,out}/ors/
```

```diff
diff --git a/config/old/ors/gnb/enb.cfg b/config/out/ors/gnb/enb.cfg
