Before this commit, we did not read the ServingCellConfigCommon (SCC) completely at start; rather, we read most (but not all) of it, then also the minRXTXTIME, and at RRC initialization in openair_rrc_gNB_configuration(), we filled the pusch-TimeDomainAllocationList into the SCC, depending on the minRXTXTIME. The reason might be that we read part of the SCC, use that to fill the NRRRC_CONFIGURATION_REQ, read also the minRXTXTIME (part of the RRC config), and then we have all we need to "finalize the SCC". Since we move everything to the MAC, I avoid too much upfront code changes, hardcode the minRXTXTIME (and check with an assert), and undo this in a later commit when the "RRC config" relevant for radio parameters, e.g., minRXTXTIME, is moved to MAC. I verified the equality of the SCC before (at the end openair_rrc_gNB_configuration()) and after (at the end of get_scc_config()) this commit manually using a printf, assuming that after RRC initialization, we didn't do any further modifications to the SCC. But in fact, I cannot know that we don't do it...
