Remove the isIntraFrequencyNeighbour field and all code that sets or
uses it, simplifying neighbour cell handling and avoiding redundant
state in the RRC gNB code. The flag duplicated information that can be
derived from the neighbour absoluteFrequencySSB and the serving cell
SSB ARFCN, and intra-frequency neighbours are logged in the SIB3
preparation flow.
Changes:
- Remove isIntraFrequencyNeighbour from nr_neighbour_cell_t in
openair2/RRC/NR/nr_rrc_defs.h
- Delete is_intra_frequency_neighbour() and
label_intra_frequency_neighbours() helpers from
openair2/RRC/NR/rrc_gNB_du.c
- Remove calls to label_intra_frequency_neighbours() from
rrc_gNB_process_f1_setup_req() and
rrc_gNB_process_f1_du_configuration_update() in rrc_gNB_du.c
- Stop setting .isIntraFrequencyNeighbour in the local
nr_neighbour_cell_t neighbourConfig initializer in
openair2/RRC/NR/rrc_gNB_mobility.c
