Convert dt-bindings pwm-fsl-ftm.txt to yaml format.
Additional change during convert:
- "big-endian" is not required property.
- Add "sleep" to pinctrl-names.
- Change pinctrl-NNN to pinctrl-0 and pinctrl-1.
- Remove label "pwm0" in example.

-The same FTM PWM device can have a different endianness on different SoCs. The
-device tree provides a property to describing this so that an operating system
-device driver can handle all variants of the device. Refer to the table below
-for the endianness of the FTM PWM block as integrated into the existing SoCs:
-
- SoC | FTM-PWM endianness
- --------+-------------------
- Vybrid | LE
- LS1 | BE
- LS2 | LE
-
-Please see ../regmap/regmap.txt for more detail about how to specify endian
-modes in device tree.
-
-
-Required properties:
-- compatible : should be "fsl,<soc>-ftm-pwm" and one of the following
- compatible strings:
- - "fsl,vf610-ftm-pwm" for PWM compatible with the one integrated on VF610
- - "fsl,imx8qm-ftm-pwm" for PWM compatible with the one integrated on i.MX8QM
-- reg: Physical base address and length of the controller's registers
-- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
- the cells format.
-- clock-names: Should include the following module clock source entries:
- "ftm_sys" (module clock, also can be used as counter clock),
- "ftm_ext" (external counter clock),
- "ftm_fix" (fixed counter clock),
- "ftm_cnt_clk_en" (external and fixed counter clock enable/disable).
-- clocks: Must contain a phandle and clock specifier for each entry in
- clock-names, please see clock/clock-bindings.txt for details of the property
- values.
-- pinctrl-names: Must contain a "default" entry.
-- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
- See pinctrl/pinctrl-bindings.txt for details of the property values.
-- big-endian: Boolean property, required if the FTM PWM registers use a big-
- endian rather than little-endian layout.
-
-Example:
-
-pwm0: pwm@40038000 {
- compatible = "fsl,vf610-ftm-pwm";
- reg = <0x40038000 0x1000>;
- #pwm-cells = <3>;
- clock-names = "ftm_sys", "ftm_ext",
- "ftm_fix", "ftm_cnt_clk_en";

- <&clks VF610_CLK_FTM0_EXT_FIX_EN>;
- pinctrl-names = "default";
