    power: Remove Wi-Fi and WWAN "power saving" toggles
    
    It's pretty clear from their experiences on smartphones that our users
    know that Wi-Fi and other wireless technologies use enough battery that
    turning them off is a power saving move.
    
    The switches and text were also pretty confusing as we would be turning
    "off" the devices to turn "on" the power saving.
