Boris BREZILLON 0903ea6017 clk: add accuracy support for fixed clock
This patch adds support for accuracy retrieval on fixed clocks.
It also adds a new dt property called 'clock-accuracy' to define the clock
accuracy.

This can be usefull for oscillator (RC, crystal, ...) definitions which are
always given an accuracy characteristic.

Binding for simple fixed-rate clock sources.
This binding uses the common clock binding[1].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible : shall be "fixed-clock".
- #clock-cells : from common clock binding; shall be set to 0.
- clock-frequency : frequency of clock in Hz. Should be a single cell.
Optional properties:
- clock-accuracy : accuracy of clock in ppb (parts per billion).
Should be a single cell.
- gpios : From common gpio binding; gpio connection to clock enable pin.
- clock-output-names : From common clock binding.
Example:
clock {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <1000000000>;
clock-accuracy = <100>;
};
