[PATCH RFT 2/2] ARM: dts: mxs: imx28: Fix NAND hierarchy description

[Stefan Wahren <wahrenst@gmx.net>]

The size-cells for GPMI are wrong in imx28.dtsi, which causes the
following warning:

    nand-controller@8000c000: #size-cells:0:0: 0 was expected

The reason for this is the definition of the partitions directly
below the nand controller node. According to nand-controller.yaml
the NAND chip must be defined as a child of the controller. Even
the fixed partitions must be kept in a partitions container.

Hi,
unfortunately i don't have access to MSR M28CU3 or an Armadeus Systems APF28
so it would be nice if someone can give a try.
