I applied the first 4 patches on the mvebu branches, the first one on
mvebu/arm64 and the 3 other on mvebu/dt64. I did this in order to not
miss the arm-soc merge window.

The binding was acked by the dt maintainer and the review of the clk
maintainer was abut the internal of the driver. The only change I did
was fixing a typo in the address part of the name of the sb-periph-clk
node as pointed by Victor Gu. I will submit a second version soon
addressing these concerns.
