backlight: aw99706: Honor the core blank state in update_status()
update_status() passes props.brightness straight to the hardware and
ignores the power/blank state tracked by the core. Writing 4 to the
bl_power sysfs attribute or blanking the framebuffer therefore leaves
the backlight lit.
Use backlight_get_brightness(), which returns 0 while the device is
blanked.
Fixes: 147b38a5ad06 ("backlight: aw99706: Add support for Awinic AW99706 backlight")
