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.

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.
