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.

3ccb1c1702 pwm: vt8500: Add polarity support 
Add support to set polarity on PWM devices, allowing for inverted
duty cycles.

Also update the binding document to #pwm-cells = <3> to allow
passing the flags from devicetree.

A binding document describing the PWM controller found on
arch-vt8500 is also included.
