PATCH v2 1/1 ARM: dts: sunxi: Add de_be0 clk parent pll to simplefb node

Avoid the parent pll for the mod-clk for de_be0 getting disabled when non of the other users are enabled (which can happen when none of i2c, spi and mmc are in use).

Note for now we point directly to the parent rather then to the de_be0 mod-clk as that is not modelled in our devicetree yet.
