ARM: dts: (apalis|colibri): unify backlight settings
This commit unifys the backlight settings. All displays sold by Toradex
are now supporting 150Hz as a PWM backlight typical frequency.
Use this value for all SoM's and put also some better default values
for different brightness.

Do not apply this patch on imx8 dts, as I will pull them in separately
later on.
