Add dt-binding documentation for s2mps15 PMIC device. The s2mps15 device
is similar to s2mps11/14 PMIC device and has 27 LDO and 10 buck regulators.

Noooo. Why "samsung,s2mps15-clk"?

Adding a new compatible to bindings is a major change so my review tag
(from v1 where there was no such compatible) should be dropped. Please
drop it.

My bad, will drop it.
