[PATCH v3] clk: add device tree fixed-factor-clock binding support

[Gregory CLEMENT <gregory.clement@free-electrons.com>]

Hi,

Since august this patch finally find a user:
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/tree/arch/arc/boot/dts/abilis_*.dtsi.
So I resusrected this patch with small changed suggested by Christian
Ruppert.

Mike,
if you still agree with this patch, you can apply it.
It was based on 3.9-rc6 but it can also be applied on clk-next
without any conflict.

Changelog:
v2 -> v3

- Updating the binding documentation bu using clock-div and clock-mul
  instead of div and mul
- Adding the tested-by tag from by Christian Ruppert

v1 -> v2
- Adding CLK_OF_DECLARE
- Using IS_ERR to test the clk value

Thanks,
