drm/panel: sony-acx565akm: Use backlight helpers
Instead of retrieving the backlight brightness in struct backlight_properties manually, and then checking whether the backlight should be on at all, use backlight_get_brightness() which does all this and insulates this from future changes. Instead of manually checking the power state in struct backlight_properties, use backlight_is_blank(). While we're at it, drop .fb_blank from the initialisation function; it is deprecated, and this helps make progress towards enabling its removal. This change makes no functional difference since FB_BLANK_UNBLANK is the default value.
