drm/panel: sony-acx565akm: Use backlight helpers

Browse Source 
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.
