5G NR: simplify init_timeshift_rotation()
...
Only Ncp1 is used, so get rid of the second timeshift_symbol_rotation array.
Also simplify the computation of "t0 * Tc * f".

changes for ulsim to get functionality back. simulation behaviour for PUSCH is not good (BLER waterfall is way too steep even if SNR threshold is ok). Note develop does more or less the same thing but SNR threshold is lower.

SC-FDMA working for 1 SNR loop (enabled using "NR_SC_FDMA" MACRO)
...
- Added nr_dft at UE side and nr_idft at gNB side
- NR_SC_FDMA can be found in "PHY/defs_nr_common.h"
- For 1 SNR loop, the code executes correctly
- For more loops, it gives a segmentation fault in the LDPC decoder
- The segmentation fault is caused when nr_idft is used
- The code works fine when the "NR_SC_FDMA" is disabled
