backlight: jornada720_bl: Introduce backlight_is_blank()

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Use the backlight_is_blank() helper to simplify the code a bit.

The jornada720_bl driver distinguish between backlight off
and brightness set to 0.

Thus this driver turn off backlight only when backlight_is_blank()
returns true.
