more changes to UE FAPI handling:

- dci_request and dl_indication for PBCH now also on stack
 - fixed type of nrUE_config (was using structure for gNB before)
 - added configuration of PBCH to phy_config_request and using this config now in phy_procedures_nr_ue
 - we need to add configuration of PDCCH and PDSCH also to phy_config_request (there are still some hardcoded parameters)
 - removed UL scheduling for now
