Laurent Pinchart ebeec0af5b pwm: Update DT bindings to reference pwm.txt for cells documentation
The PWM client cells format is documented in the generic pwm.txt
documentation and duplicated in all PWM driver bindings. Remove
duplicate information and reference pwm.txt instead.

NXP PCA9685 16-channel 12-bit PWM LED controller
================================================
Required properties:
- compatible: "nxp,pca9685-pwm"
- #pwm-cells: Should be 2. See pwm.txt in this directory for a description of
the cells format.
The index 16 is the ALLCALL channel, that sets all PWM channels at the same
time.
Optional properties:
- invert (bool): boolean to enable inverted logic
- open-drain (bool): boolean to configure outputs with open-drain structure;
if omitted use totem-pole structure
Example:
For LEDs that are directly connected to the PCA, the following setting is
applicable:
pca: pca@41 {
compatible = "nxp,pca9685-pwm";
#pwm-cells = <2>;
reg = <0x41>;
invert;
open-drain;
};
