ipq806x: opp/core: fix broken patch Handle opp voltage adjust

Browse Source 
The opp_notifier introduced with patch 0054-Handle-OPP-voltage adjust
for some reason missed the actual registration in the opp struct,
resulting in never being registred.
This was present in kernel 4.9 patchset but dropped in the transition
 to 4.14. Reintroduce this and fix patch 0055 about L2 cache scaling.
