[RFC 12/12] ARM64: dts: marvell: use reworked NAND controller driver on Armada 7K/8K

[Miquel Raynal <miquel.raynal@free-electrons.com>]

Change the bindings to use the reworked Marvell NAND controller driver.
Also adapt the nand controller node organization to distinguish which
property is relevant for the controller, and which one is NAND chip
specific. Expose the partitions as a subnode of the NAND chip.

Remove the 'marvell,nand-enable-arbiter' property, inefective with
Armada boards.
