Parminder Singh ec0aea2374 Removed separate LLR calculation for PTRS 
- New Data Structure to store PTRS RE's is removed
- LLR's are calculated at the end symbol for whole slot

Parminder Singh b288eafd1e Common Phase error estimation and compensation in uplink. 
FEATURE STATEMENT:
- Introduce linear phase error noise model in Uplink at UE
- Perform common phase error (CPE) estimation and compensation at gNB

SOLUTION:
- A linear phase shift model is introduced in simulation.
- PTRS symbols are used to perform estimation of CPE from DMRS compensated signal
- The estimated values are interpolated in time domain and signal is compensated for the CPE.
- PTRS processing is done in Frequency Domain for each symbol in a slot and
  LLR's are calculated for each symbol accordingly.

IMPLEMENTATION:
* sim.h/channle_sim.c
- Linear Phase Noise Generation model definition.
* nr_ul_channel_estimation.c/nr_ul_estimation.h
- CPE estimation from PTRS and DMRS compensated signal.
* nr_dmrs_rx.c/nr_refsig.h
- Regenerate PTRS symbols at gNB.
* nr_ulsch_demodulation.c
- Removed old PTRS processing code and move to a common PTRS processing function
* defs_gNB.h/init.c
- New PTRS variables definition and initialization
* nr_ulsch_ue.c
- Corrected PTRS parameter to get new PTRS symbols for each OFDM symbol

TESTING
* ulsim.c
- Added Phase noise, Enable PTRS signal and verified the output.

VERIFICATION
- The LLR are rotated back with estimated CPE and no error is observed in scrambling/decoding

cig eb7f3193aa Enabled compute_nr_prach_seq to be used at both gNB and UE side: 
- now the function gets more input arguments but can be used from both UE and gNB
- this change was needed because the prach fapi of UE differs from the gNB one

Thomas Schlichter 8fbdfa39ec disable PUSCH PTRS for now 
As adding PTRS leads to shortening of the coded data, redudandency is removed and the performance decreases on a pure AWGN channel.
So PTRS should only be enabled if phase noise is present.
