software/ors-amarisoft: enb: nr: Let root_sequence_index to also be cell parameter

For uniformity with LTE where it already is.

We do not expose it in ORS schema because it will be exposed only in generic
LTE and NR schemas, but for ORS schemas I prefer to keep them intact myself.

Tests will be added later as full tests for generic MultiRU.

Backward compatibility: no change for ORS and everything else.
