FWIW that's likely a hack (because IIUC it needs to power up some
regulator for the sensor devices to work) but that's "fine"
I don't know if there's a better way to handle it though.. I think it's
a board design "issue", since the DSP has access to some GPIOs but it
seems like that wasn't utilized
I'm open to suggestions
