The PCA955x driver since it was merged has added a "pca955x:" prefix to
LED names. This meanas platform data (such as the device tree) cannot
fully control the name. Here's what this produces using the example in
the device tree bindings:

  # cat /sys/class/leds/
  pca955x:green:power/
  pca955x:pca9552:white/
  pca955x:pca9552:yellow/
  pca955x:red:power/

Some systems want the ability to configure the full string. To do this,
introduce a build time option that adds the prefix that defaults to
enabled in order to preserve existing behaviour.
