- removed unused arguments to phy functions
- removed irrelevant conditions on UE run mode
- replaced hardcoded param with PHY UE stored value

- replaced eNB naming with gNB

The LDPC lifting size has to be stored for each harq_process as its only assigned in the first round.

This reverts commit 199ce5d9.

If UE receives retransmission for already decoded PDSCH, it skips decoding and sets ACK directly.
And adding PDSCH decoding stats and printing then every 64 frames for CI purpose

The BG was set to its default for rounds > 0. This is now fixed by adding it to harq structure.
Also a fix for wrong I_lbrm set in dlsch decoding.

- Initialized variable to remove the valgrind issue.

- updated return function value to -1
- removed static variable for dmrs symbol selection for channel
- Updated sin cos quadrant check conditions
- removed casting from PTRS slope and related calculations

- fixed channel compensation by choosing most recent DMRS symbol ina
  slot
- Removed code to find nearest DMRS symbol for channle compensation
- Updated TBS calculation in DLSIM
- Added debug prints in PTRS CPE estimation for DMRS symbol

- -U 2 0 [0-2], can be used to update DMRS configurations
- update check for additional position 3 in dlsch decoding

- Added PTRS extraction and estimation for DL
- Added processing for whole slot wrt PTRS estimates
- DLSIM is updated to used -T flag to enable PTRS
- DMRS compensated signal is further compensated with PTRS estimation

- removed redundant initialisation of variables
- introduced two "RF helpers" function that are replacing shared code in the sync routines
- added a new .c file and updated the cmakelists and .h files

- LLR calculations are moved inside a static function and done for a
  slot in last symbol processing

- Added PTRS variables in transport UE header file
- Added DMRS inline symbol check function in refsig.h
- Added PTRS estimation and other related structures in defs_nr_UE.h file
