power: supply: sbs-battery: Add PbAc, NiZn, RAM, and ZnAr support
Add support for PbAc, NiZn, RAM, and ZnAr chemistries as defined in the
Smart Battery Data Specification v1.1 (Section 5.1.30 DeviceChemistry).
Currently, the sbs-battery driver only handles LION, LiP, NiCd and NiMH.
The Smart Battery specification defines 8 possible values:
- Lead Acid (PbAc)
- Lithium Ion (LION)
- Nickel Cadmium (NiCd)
- Nickel Metal Hydride (NiMH)
- Nickel Zinc (NiZn)
- Rechargeable Alkaline-Manganese (RAM)
- Zinc Air (ZnAr)
- Lithium Polymer (LiP)
