Convert the Freescale General Purpose Timer binding to DT schema format.
Add the specific compatibles in use. Drop the "fsl,cpm2-gtm" compatible
which is not used. The examples are all similar, so just leave 1
example.

-Required properties:
- - compatible : should be
- "fsl,<chip>-gtm", "fsl,gtm" for SOC GTMs
- "fsl,<chip>-qe-gtm", "fsl,qe-gtm", "fsl,gtm" for QE GTMs
- "fsl,<chip>-cpm2-gtm", "fsl,cpm2-gtm", "fsl,gtm" for CPM2 GTMs
- - reg : should contain gtm registers location and length (0x40).
- - interrupts : should contain four interrupts.
- - clock-frequency : specifies the frequency driving the timer.
-
-Example:
-
-timer@500 {
- compatible = "fsl,mpc8360-gtm", "fsl,gtm";
- reg = <0x500 0x40>;
- interrupts = <90 8 78 8 84 8 72 8>;
- interrupt-parent = <&ipic>;
- /* filled by u-boot */
- clock-frequency = <0>;
-};
-
-timer@440 {
- compatible = "fsl,mpc8360-qe-gtm", "fsl,qe-gtm", "fsl,gtm";
- reg = <0x440 0x40>;
- interrupts = <12 13 14 15>;

I'm not applying this one, it was already converted by patch:
