[PATCH] dt-bindings: power: Bindings for Samsung batteries

This adds device tree bindings for Samsung SDI batteries.
Everything can be determined from the product number so the entire
battery is just a specific compatible string.

+description: |
+  Samsung SDI (Samsung Digital Interface) batteries are all different versions
+  of lithium ion chemistry devices used for mobile phones, laptops and other
+  portable electronics. The batteries are adapted to a specific product and
+  the physical restrictions make it impossible to use another battery with the
+  product, so product device trees can specify these batteries. Operating
+  systems should determine hardware characteristics of the batteries from the
+  compatible string.

Sebastian: can this be merged? I am working on corresponding code
for Linux to populate Samsung batteries from compatible.
