ARM: dts: imx6: Move nodes which have no reg property out of bus

Move tempmon, ldb and pmu nodes from soc node to root node.

The nodes that have been moved do not have any register properties and thus
shouldn't be placed on the bus.

This fixes the following build warnings with W=1:

arch/arm/boot/dts/imx6dl-apf6dev.dtb: Warning (simple_bus_reg): Node /soc/aips-bus@2000000/tempmon missing or empty reg/ranges property
arch/arm/boot/dts/imx6dl-apf6dev.dtb: Warning (simple_bus_reg): Node /soc/aips-bus@2000000/ldb missing or empty reg/ranges property
arch/arm/boot/dts/imx6dl-apf6dev.dtb: Warning (simple_bus_reg): Node /soc/pmu missing or empty reg/ranges property

Based on a patch from Simon Horman for r8a7795.dtsi.
