Merge tag 'clk-mvebu-3xx-3.15-2' of git://git.infradead.org/linux-mvebu into clk-next-mvebu

clock: mvebu new SoC changes for v3.15 (incremental pull #2)

 - mvebu (Armada 375)
    - fix ratio register offest

 - mvebu (Armada 380)
    - expand core divider clock driver to support 380 SoC (enables nand support)
