Armada 380 NAND support

This patchset adds support for the NAND on Armada 380/385 SoCs.

The first patch adds a new "armada-380-corediv-clock" compatible string, with its proper SoC-specific structure, adding the register layout for this SoC family.

The second and third patches add the devicetree changes to support the Core Divider clock.

After adding its clock source, the fourth and fifth patches add the NAND devicetree changes. The NAND controller is compatible with the Armada 370 controller, so we are currently support it using the same compatible string.

The last patch updates the binding documentation for the Core Divider clock, which is missing the information about the already supported Armada 375 compatible string.

This series is based on linux-next 20140307. I expect it will apply cleanly on v3.15-rc1; if that's not the case, I'll send a rebased patchset.

The clock and devicetree changes are mostly independent so they can be merged through the clock and mvebu tree respectively.

Changes from v2:

* Removed the unneeded 'nand' label from the flash at d0000 node.

* Renamed 'coredivclk at e4250' to 'clock at e4250' according to ePAPR recomendation, below.

Changes from v1:

* Changed nand at d0000 with flash at d0000 in the devicetree. The latter is compliant with ePAPR recomendation (see ePAPR v1.1, section 2.2.2, Generic Names Recommendation).
