[U-Boot] [PATCH v3 2/4] arm: mvebu: NAND clock support for MSYS devices

[Chris Packham]

One difference with the integrated CPUs is that they use a different
clock control block to the Armada devices. Update mvebu_get_nand_clock()
accordingly.

This could probably be squashed into the previous change. I was trying
to separate things to aid review but it's hard to do so and keep
bisectability.

Changes in v3: None
Changes in v2: None
