remove ThermalManager
It throttles 1000x more than intended, and I suspect that some of the trip points it uses to decide when to throttle make no sense. We've already turned it off on the Nexus 5x.

|

* Inside each thermal_zone folder is a file called 'temp,' which has the current temperature

|
||||
*
|
||||
* When the reading in temp is greater than one of the numbers in the trip_point files, then the
|
||||
* kernel will take some kind of action. This is all documented online.
|

*
|

* In any case, the goal of this class is to sleep right before a trip point is about to be
