Subject: [PATCH v2 2/4] dt-bindings: leds: commonize leds property

A number of existing schemas use 'leds' property to provide
phandle-array of LED(s) to the consumer. Additionally, with the
upcoming privacy-led support in device-tree, v4l2 subnode could be a
LED consumer, meaning that all camera sensors should support 'leds'
and 'led-names' property via common 'video-interface-devices.yaml'.

To avoid dublication, commonize 'leds' property from existing schemas
to newly introduced 'led-consumer.yaml'.
