Also updating pdcch_config for SIB1

Deletes the second_addr parameter in all files that also use the
mgmt_addr=192.168.18.240 (asterix's N310).

We seprarated out the large if block in the push/pull
of the UL_TTI_REQ fields to make it easier to read
and debug. Furthermore, we add in AsserFatals before
indexing in UL_TTI_REQ PDU list to ensure we are not
indexing past the end of the array.
