dt-bindings: cpufreq: remove stale arm_big_little_dt entry
Most of the ARM platforms used v2 OPP bindings to support big-little configurations. This arm_big_little_dt binding is incomplete and was never used. Commit f174e49e4906 (cpufreq: remove unused arm_big_little_dt driver) removed the driver supporting this binding, but the binding was left unnoticed, so let's get rid of it now.

-Generic ARM big LITTLE cpufreq driver's DT glue
------------------------------------------------
-
-This is DT specific glue layer for generic cpufreq driver for big LITTLE
-systems.
-
-Both required and optional properties listed below must be defined
-under node /cpus/cpu@x. Where x is the first cpu inside a cluster.
-
-FIXME: Cpus should boot in the order specified in DT and all cpus for a cluster
-must be present contiguously. Generic DT driver will check only node 'x' for
-cpu:x.
-
-Required properties:
-- operating-points: Refer to Documentation/devicetree/bindings/opp/opp.txt
- for details
-
-Optional properties:
-- clock-latency: Specify the possible maximum transition latency for clock,
- in unit of nanoseconds.
-
-Examples:
-
-cpus {
- #address-cells = <1>;
- #size-cells = <0>;
-
- cpu@0 {
- compatible = "arm,cortex-a15";
- reg = <0>;
- next-level-cache = <&L2>;
- operating-points = <
- /* kHz uV */
- 792000 1100000
- 396000 950000
- 198000 850000
- >;
- clock-latency = <61036>; /* two CLK32 periods */
- };
-
- cpu@1 {
- compatible = "arm,cortex-a15";
- reg = <1>;
- next-level-cache = <&L2>;
- };
-
- cpu@100 {
- compatible = "arm,cortex-a7";
- reg = <100>;
- next-level-cache = <&L2>;
- operating-points = <
- /* kHz uV */
- 792000 950000
- 396000 750000
- 198000 450000
- >;
- clock-latency = <61036>; /* two CLK32 periods */
- };
-
- cpu@101 {
- compatible = "arm,cortex-a7";
- reg = <101>;
- next-level-cache = <&L2>;
- };
-};
