The node names for devices using the pwm-leds driver follow a certain
naming scheme (now). Parent node name is not enforced, but recommended
by DT project.

Notes:
v7 -> v8:
* rebased on v5.10-rc1
* updated indexes and added comment (Ahmad Fatoum)
v6 -> v7:
* split up patch (one per sub arch)
* added actual warnings to commit message
