[CI] for gNB Phy test : update of the execution timings ref values, according to the latest developments

MR !1197 : dongzhanyi-zte-develop1
function nr_generate_dci_top and nr_generate_dci has the frame_parms parameter, whose type is the structure NR_DL_FRAME_PARMS.
The better way is to pass the parameter as a pointer. 

MR !1176 : NR_phytest_bugfixes
This fixes a bug for configurations with less than 50 PRBs in phy-test mode.

MR !1142 : nr-dl-mimo-2layer

-fixes UL iperf log collection/analysis for UE module
-fixes iperf processes mgt for UE module

But that part should be moved to the MAC anyways

I have to revert this to be consistent with the OAI gNB.
But I think it is wrong to take the BWPSize from scc or scc_SIB, and the BWPStart from DLbwp[0].

MR !1188 : NR_gNB_initial_MIB_fix  
This MR fixes a bug for which the gNB would send an empty MIB in the first frames of execution. This is because MIB is generated every 8 frames but the first MIB wouldn't be generated before frame 8 at the beginning of each run.

MR !1184 : x2_handle_sctp_shutdown
Avoid eNB exiting after gNB tries to reconnect over X2 for NSA

This reverts commit b38cc832.

Merge branch 'develop' of gitlab.eurecom.fr:oai/openairinterface5g into x2_handle_sctp_shutdown
