ARM: dts: rockchip: add rk3288-veyron-jaq backlight and panel overrides
The panel which jaq uses requires the pwm duty cycle larger than 3%,
when the backlight status from power off to power on, otherwise the
backlight will flush, so we modify the second brightness-level to 8,
and when the backlight from power off to power on the pwm duty cycle
will larger than 3%.
