ACPI / Battery: Update information on info notification and resume

A notification event 0x81 from an ACPI battery device requires us to
re-read the battery information structure.  Follow this requirement
and remove and re-create the battery's attibutes in sysfs so that
they reflect the reporting units used by the battery at the moment
(those units may actually change sometimes at run time, which happens
on some Thinkpads).

The approach used in this patch was suggested by Matthew Garrett.
