Jyri Sarha c873d14d30 clk: add gpio gated clock
The added gpio-gate-clock is a basic clock that can be enabled and
disabled trough a gpio output. The DT binding document for the clock
is also added. For EPROBE_DEFER handling the registering of the clock
has to be delayed until of_clk_get() call time.

Binding for simple gpio gated clock.
This binding uses the common clock binding[1].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible : shall be "gpio-gate-clock".
- #clock-cells : from common clock binding; shall be set to 0.
- enable-gpios : GPIO reference for enabling and disabling the clock.
Optional properties:
- clocks: Maximum of one parent clock is supported.
Example:
clock {
compatible = "gpio-gate-clock";
clocks = <&parentclk>;
#clock-cells = <0>;
enable-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
};
