    backlight: lp8788: Fully initialize backlight_properties during probe
    
    [ Upstream commit 392346827fbe8a7fd573dfb145170d7949f639a6 ]
    
    props is stack allocated and the fields that are not explcitly set
    by the probe function need to be zeroed or we'll get undefined behaviour
    (especially so power/blank states)!
