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)!
