Label is used for naming LED class devices. Since ePAPR
doesn't require uniqueness for label properties, it has to be
explicitly required in the LEDs common bindings documentation.

document bindings.

Update comment about gpio-cells which says not correctly to be set to 0.
When we want to reference tca6507 gpio #gpio-cells must be set to 2 (it is
already correct in example).
