LP55xx family devices have internal three program engines which are used for
loading LED patterns.
To maintain legacy device attributes, specific data structure is used, 'mode'
and 'led_mux'.
The mode is used for showing/storing current engine mode such like disabled,
load and run.
Then led_mux is used for showing/storing current output LED selection.
This is only for LP5523/55231.
