power: Clarify suspend signal monitoring comment

We need to both watch for the signal and setup inhibitors
to be informed about suspend attempts, so move the comment
above both calls.

power: Call backlight_enable() after session setup

backlight_enable() does 2 things, fiddle with the DPMS as well
as attempt to claim the light sensor. But the light sensor
claim attempt will always fail as the "session_is_active" variable
has not been initialised yet. So just try a tad later for it
to work as soon as you've logged into the session.

power: "0.0" is not a valid light level

This is the equivalent of "undefined" for the accelerometer
orientation. Don't use it to prime our nice ambient light
readings curve.
