[PATCH] ARM: dts: add the AB8500 clocks to the device tree

[Linus Walleij]

This adds the AB8500 clocks to the device tree using the new
bindings from the clk subsystem, making audio work again.

ARM SoC guys: please consider this for late merge/early fix.

Lee had audio working at some point in the past, but there is no
way of fixing it backward or for stable. However: applying this
fixes it for v4.11.

ChangeLog v1->v2:
- Rename DT node to clock-controller.
