[PATCH 1/2] dt-bindings: hwmon: add binding documentation for adt7475

[Chris Packham]

With the addition of the invert-pwm property the adt7475 needs its own
binding documentation rather being captured under trivial-devices.txt.

+- invert-pwm: This configures the PWM to use logic low for 100% duty cycle.
