Subject: [PATCH leds v2 20/50] leds: pm8058: use struct led_init_data when registering

By using struct led_init_data when registering we do not need to parse
`label` DT property. Moreover `label` is deprecated and if it is not
present but `color` and `function` are, LED core will compose a name
from these properties instead.
