Rakesh Mundlamuri f84ed0bbcf Make nb_antenna as a input parameter to generate_srs_nr() 
- We use the same function at gNB and UE.
 - We always use nb_antennas_tx to check the max possible number of ports (which is wrong).
 - At gNB, we should use nb_antennas_rx and at the UE, we should use nb_antennas_tx.

NR UE: fix bug for SRS generation when freqDomainShift (n_shift) is not 0

According to TS 38.211 section 6.4.1.4.3, the frequency domain shift value
n_shift is from higher-layer parameter freqDomainShift. The quantity n_RRC
is given by higher-layer parameter freqDomainPosition. Also corrected
k_0_overbar_p calculation formula to align with standard.

Sakthivel Velumani 6128d1bb62 Use common function to generate CSI-RS signal 
The functions nr_generate_csi_rs() and nr_ue_generate_csi_rs() are
identical. This commit removes nr_ue_generate_csi_rs() and moves
nr_generate_csi_rs() to nr_phy_common_csirs.c so both gNB and UE can use
the same function.
