dt-bindings: pwm: Add STM32 bindings

Define bindings for pwm-stm32

version 9:
- change commit message header

version 8:
- reword st,breakinput description.

version 6:
- change st,breakinput parameter format to make it usuable on stm32f7 too.

version 2:
- use parameters instead of compatible of handle the hardware configuration

STMicroelectronics STM32 Timers PWM bindings
Must be a sub-node of an STM32 Timers device tree node.
See ../mfd/stm32-timers.txt for details about the parent node.
Required parameters:
- compatible: Must be "st,stm32-pwm".
- pinctrl-names: Set to "default".
- pinctrl-0: List of phandles pointing to pin configuration nodes for PWM module.
For Pinctrl properties see ../pinctrl/pinctrl-bindings.txt
Optional parameters:
- st,breakinput: One or two <index level filter> to describe break input configurations.
"index" indicates on which break input (0 or 1) the configuration
should be applied.
"level" gives the active level (0=low or 1=high) of the input signal
for this configuration.
"filter" gives the filtering value to be applied.
timers@40010000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "st,stm32-timers";
reg = <0x40010000 0x400>;
clocks = <&rcc 0 160>;
clock-names = "clk_int";
pwm {
compatible = "st,stm32-pwm";
pinctrl-0 = <&pwm1_pins>;
pinctrl-names = "default";
st,breakinput = <0 1 5>;
