Add Critical and hot trips for emergency system shutdown and limiting
system load.

Change passive trip to active to make sure fan is activated on the
lowest trip.

Rule of thumb is that each commit has to build on its own: this will break build
because of mt7986a-bananapi-bpi-r3.dts referencing the now unexistant
cpu_trip_passive phandle.

Solving that is simple.
Merge commit [2/3] and [3/3] in a single commit.

Obviously, retain both fixes tags :-)

Cheers,
Angelo
