PTRS leads to code shortening, and the current LDPC implementation has issues with that for higher code rate.
Because of this, we have to disable PTRS by default, as we test MCS 28 in CI.

   - if L_ptrs is >= number of pusch symbols, then no ptrs will be scheduled

   - The bug occurs when the PUSCH allocation contains the central RB of the whole UL BW

Using ul_dmrs_symb_pos at UE side instead of assuming that DMRS is only present at 1st symbol of PUSCH

  - Using the implemented DMRS functionalities at the MAC layer at the gNB side
  - Removing is_dmrs_symbol function
  - Temporary implemetation at the UE side considering DMRS symbol is at the 1st PUSCH symbol,
    until the nFAPI structs for DMRS is adopted at the UE side

Nr rrc configuration

See merge request oai/openairinterface5g!738

inline alone does only define a function without a corresponding
declaration. static solves this problem

rfsim works

an assertion fails in gnb (need to be fixed)
