The "shell service call power ..." is probably just a runtime setting?
so we have to run it on every boot, no?

Can we add this to a generic place in lava-android-test (or
dispatcher) to ensure we call this first thing every time when booting
up a unit?

I shoved it temporarily into my dispatcher running locally.  A better solution going forward is to probably allow for some board-defined extra setup steps that run right after boot.  In this case, I also had to add a sleep for about 15 seconds because this service doesn't seem to be available as soon as the board is booted.

It does work great though, and I'm able to keep the board up and running with it!  Thanks for figuring this out Yongqin!
