Robert Schmidt c930563929 Move radio configuration parameters to MAC, SIB1 not initialized! 
!SIB1 is not correctly filled! This commit does not work with COTS UEs!
The next commit fixes this.

- Move radio config (e.g., minRXTXTIME, SIB1 TDA, do_SRS, etc) down to
  MAC.
- Some parameters in MAC are redundant: delete them.
- Remove call to nr_mac_config_scc() from RRC and simulators, the MAC
  initialization routine calls it implicitly

Robert Schmidt 5d0ae84ad2 Move MIB to MAC 
The MasterInformationBlock is handled at the DU and sent to the CU in
the F1 Setup Response. Hence, move it down to the MAC. Furthermore:

- Change type because MIB_PDU_t is 4G type
- Simplify schedule_nr_mib()

Robert Schmidt 0f897b4007 Move ServingCellConfigDedicated to MAC 
As with the ServingCellConfigCommon, the ServingCellConfigDedicated is a
radio-related structure to be handled at the DU.
 2023-09-22 08:22:15 +02:00
Robert Schmidt 2b29531591 Move ServingCellConfigCommon to MAC 
Note: the reestablishment is broken, and a later commit fixes it.

The ServingCellConfigCommon is an inherently radio-related
configuration. As such, it should be handled by the DU, not the CU.
Therefore, move it "down" to the MAC.
