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.

Fixes: 1f5be05132f3 ("arm64: dts: mt7986: add thermal-zones")
Fixes: c26f779a2295 ("arm64: dts: mt7986: add pwm-fan and cooling-maps to BPI-R3 dts")
Suggested-by: Daniel Golle <daniel@makrotopia.org>
