[PATCH 1/3] Documentation: devicetree: add pxa3xx compatible and syscon property

[Miquel Raynal]

Document the new pxa3xx_nand driver compatible string for A7k/A8k SoCs
that need to access system controller registers in order to enable the
NAND controller through the use of a phandle pointed to by the
'marvell,system-controller' property.
