Add a label for the cpu node, so that board devicetree files can
reference to the CPU node.

This is useful for describing a PMIC voltage that supplies the CPU
voltage.

For example:

Additional device tree overlays can be used for any accessories that

The parallel RGB interface (lcd_display) and all related nodes can
be enabled in an overlay if used. Keep all nodes disabled in the
module-level device tree.
Rename display interface node to match imx6qdl-apalis
