The .s_power() callback is deprecated, and now that we have pm_runtime
functionality in the driver there's no further use for it. Delete the
function.

Could this be written as part of the power-on sequence after identifying
the sensor? Likewise in probe() if it's possible the device won't be
powered down before it gets used --- I guess nothing rules that out?
