[RFC PATCH v3 9/9] arm64: dts: lx2160a: fix FlexSPI clock

[Michael Walle]

Now that we have a proper driver for the FlexSPI interface use it. This
will fix SCK frequency switching on Layerscape SoCs.

Thanks to Vladimir Oltean, this was partially tested on a LX2160A RDB. But
this patch is marked as RFC nonetheless, because there is too much
difference in the clock tree between LS1028A and LX2160A. It would be nice
if someone could test it and add a Tested-by.

Changes since v2:
 - none
