[PATCH] ARM: dts: imx: Fix the assigned-clock mismatch issue on imx6q/dl

[Bai Ping]

The 'assigned-clock-parents' and 'assigned-clock-rates' list
should corresponding to the 'assigned-clocks' property clock list.

As this essentially a fix to ed339363de1b ("ARM: dts: imx6qdl-sabreauto:
Allow HDMI and LVDS to work simultaneously"), I'm going to send it as a
fix with copying stable.

@Fabio,

Do you agree with the fix?

Actually the mismatch exists since 97dae8590fa314c ("ARM: dts:
imx6qdl-sabreauto: Add audio support").

It seems that even after this patch we still have a mismatch:
assigned-clocks has 5 members and assigned-clock-parents has 4.

I think if it is the last clock in the assigned-clock list, the 
corresponding
'assigned-clock-parents' and 'assigned-clock-rates'  entry can be omitted.

Yes, you are right. Confirmed with
Documentation/devicetree/bindings/clock/clock-bindings.txt and your
patch is correct, thanks:
