Update NR P5 and P7 nFAPI headers to have 32-bit message_length
In the NR functions, this causes the header parameters following message_length to have their position shifted by 2 bytes, due to the increase in message_length size.
Change needed to accommodate SCF222.10.02 Table 3-3
Separates nfapi_p4_p5_message_header_t and nfapi_nr_p4_p5_message_header_t
Change the callbacks signature to accept/return void* intead of expecting a particular header type, being the NR/LTE distinction done inside the callback functions.
Create NR related functions for nFAPI transmit timestamp and checksum calculation.
Move nfapi_p7_codec_config_t and nfapi_p4_p5_codec_config_t to separate header to be shared between LTE and NR VNF/PNF
Move nfapi_nr_timing_info_t into NR header.
Move NR specific function declarations to NR header.
Fix Assert condition to properly check that body was packed successfully
Fix retval value when performing bitwise AND with push16
Remove commented code
The previous code fills random number in the TDD config, which leads to
unrealistic TDD patterns. Filling wtih a specific, realistic TDD config
allowed to fix the bug in the next commit.
