Draft: NR FDD Band n1 with COTS UE and B210

Add FDD configuration file:

• Band n1
• 15 kHz SCS
• 10 MHz BW

This MR depends on MR !2445 (merged)

This configuration file is intended to be used with USRP B210 on the gNB side and was successfully tested with COTS UE (Quectel RM510Q-GL, iPhone 14 Pro)

How to run:

cd ~/openairinterface5g
source oaienv
cd cmake_targets/ran_build/build
sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band1.u0.52PRB.usrpb210.conf --continuous-tx
