[PATCH v6 2/7] dt-bindings: leds: add default-brightness property to common.yaml

["Jean-François Lessard" <jefflessard3@gmail.com>]

Add default-brightness property to leds/common.yaml to establish a single
canonical definition for LED brightness initialization.

The property is currently defined locally in leds/leds-pwm.yaml and is
needed by auxdisplay/titanmec,tm16xx.yaml. Properties should be defined
in only one location to avoid type inconsistencies across bindings.
