[nrf toup][nrfconnect] Added missing GetSoftwareVersionString impl

The basic information cluster implementation started to use
DeviceInfoProvider instead of ConfigurationMgr. Because of that
GetSoftwareVersionString returns not implemented error code,
as nrfconnect provider does not override this method.
