This adds a battery-type property and bindings for the different
"technologies" that are used in Linux. More types can be added.
This is needed to convert the custom ST-Ericsson AB8500 battery
properties over to the generic battery bindings.

ChangeLog v1->v2:
- Add devicetree list to Cc
- Use "device-chemistry" instead of "battery-type" as this
has precedence in standards.
I need a bunch of new bindings for switch the STE AB8500 custom
bindings out, but I need to start somewhere, this is as good as
any place to start.
