Hi!

WLED4 peripheral is present on some PMICs like pmi8998
and pm660l. It has a different register map and also
configurations are different. Add support for it.

I'm not sure if this change of format is good idea here...

This format is clean and easily readable. That's why I have moved to this format. To avoid confusion, I will move out the existing properties (pm8941-wled.c) to other
patch. So that it will be easy to review.
