power: supply: core: Add additional health status values
Some batteries can signal when an internal fuse was blown. In such a
case POWER_SUPPLY_HEALTH_DEAD is too vague for userspace applications
to perform meaningful diagnostics.
Additionally some batteries can also signal when some of their
internal cells are imbalanced. In such a case returning
POWER_SUPPLY_HEALTH_UNSPEC_FAILURE is again too vague for userspace
applications to perform meaningful diagnostics.
Add new health status values for both cases.
