Subject: ACPI / SBS: Enable battery manager when present

commit 61f8ff693923e4b19748b0e8287b99778f2661c7 upstream.

Commit 9faf6136ff46 (ACPI / SBS: Disable smart battery manager on
Apple) introduced a regression disabling the SBS battery manager.
The battery manager should be marked as present when
acpi_manager_get_info() returns 0.
