wifi: iwlwifi: cfg: minor fixes for Sc

Remove the erroneously named IWL_DEVICE_BZ_COMMON macro
from the Sc file and fix some indentation. Also bump the
minimum FW version since it's not released yet anyway,
right now this is mostly to make the config different
from iwl_bz_cfg which would otherwise be the same with
the upcoming transport config cleanups.
