The original patch over rode the nf_conntrack_un/register_notifier API, which will
break other modules relying on the API. Reworked the notification APIs to play nice
with others. Also avoid to touch the code of fullcone nat.

* mtwifi: mt7615: fix multi-profile merge

Currently some settings like AutoChannelSelect, CountryRegion(ABand),
HT_BW/VHT_BW are not respected. This is due to wrong multi-profile
merging when l1profile.dat is not consistent with compiling flag
DEFAULT_5G_PROFILE.

5g profile should be put before 2g profile when DEFAULT_5G_PROFILE is
set.
