- 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

- 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

- Based upon ptrs bitmap, ptrs symbols are added in DL
- Mac ptrs validation condition is updated

- Get RRC values from dedicated bandwidth part and process it
- Validate all settings in MAC layer and enable PTRS processing in PHY

- PTRSPortIndex, PTRSTimeDensity, PTRSFreqDensity, PTRSReOffset, nEpreRatioOfPDSCHToPTRS
- mcs_table : to calculate MCS table in MAC layer and pass tp PHY
- pduBitmap : same as used in DL FAPI interface, to enable or disable PTRS processing

- Added a function to add PTRS values in RRC context.
- This function can be used to overwrite the PTRS values also.
- When RRC config file contains PTRS values then this function can be used
respectively in RRC context.

This reverts commit 1a5874d4.

Various mutexes are present in the phy_stub_UE.c file. However, it will
only be run in a single thread; the multiple-thread implementation also
runs the higher layers concurrently, which leads to races and segfaults.
Therefore, remove these mutexes, as we don't need them.
