Generate SRS sequence for every received SRS signal

For example, when there is BWP switch, we were using a wrong SRS sequence for the new BWP (and SRS configuration). Therefore, in this MR, we generated the SRS sequence for every received SRS signal.

can you please say a word about why this change is necessary?

@schmidtr It was added in the Description of MR.

Yes, generating at every instance seems the sensible thing to do for PHY. If it is a very time consuming procedure, then a better implementation is required to avoid recomputing. For now it is an acceptable modification to me.

@francescomani We measured the time, and it takes on average 2us (1/10 of time of SRS channel estimation). For us it looks a acceptable time and it is only recomputed as our current configuration at every 160 slots: srs_res0->resourceType.choice.periodic->periodicityAndOffset_p.present = NR_SRS_PeriodicityAndOffset_PR_sl160;
