[PATCH 1/2 v4] clk: add DT bindings header for Gemini clock controller

[Linus Walleij <linus.walleij@linaro.org>]

This adds the DT binding macros used by the clock controller.

Acked-by: Rob Herring <robh@kernel.org>

Mike/Stephen: please merge this into the clock subsystem once
you're happy with it. Sorry for the back-and-forth. I will
deal with the ARM SoC DTS landing orthogonally.

The DTS files will be submitted with numerical values for
the reset lines, then a follow-up patch after -rc1 will
switch to using defines. This strategy was adviced by the
ARM SoC maintainers.

ChangeLog v1->v4:
- New file to merge the macros in isolation from the
  DT bindings and implementation.

The bindings themselves will be merged as part of the DTS updates
through the ARM SoC tree.
