ibmaem: don't query the entire sensor repository when reading energy meter
Currently, all sensors are read when the energy meter is queried via
sysfs. This introduces a considerable amount of delay and variation in
the sysfs reading, which is not desirable when trying to profile energy
use. Therefore, read only the energy meters when a sysfs query comes in
for them, and don't cache the results so that we always get the latest
reading.
