Douglas Teles 5f1f6182cf fake-suspend: cut the panel backlight even when DPMS handles the blank
The compositor path blanked the framebuffer but could leave the panel
backlight powered, so the "sleeping" console showed a black yet lit
screen and kept burning the display power budget. Turn the backlight
off through bl_power in both paths and restore it on wake.
