rockchip/rk3288: use bl_en instead lcd_bl to fill_lb_gpio

Browse source 
in depthcharge we will use "backlight" gpio which in lb_gpio table
to control backlight, we use lcd_bl before, but it will not meet
the backlight power sequence, so we change it to bl_en.

BUG=chrome-os-partner:37348
TEST=Boot from speedy, and backlight work well
BRANCH=None
