[PATCH v2 1/2] power: supply: Add PbAc, NiZn, RAM, and ZnAr support

[Boris Shtrasman <borissh1983@gmail.com>]

Add four new members to the POWER_SUPPLY_TECHNOLOGY
enum and sysfs interface to represent the Smart Battery
Data Specification v1.1 (Section 5.1.30 DeviceChemistry) battery types:

 - Lead Acid (PbAc)
 - Nickel Zinc (NiZn)
 - Rechargeable Alkaline-Manganese (RAM)
 - Zinc Air (ZnAr)

Update documentation to express these types.
Update ABI testing for these types.
