This is a follow-up patch to the previous one, which fixed a
race-condition during registration of the attribute group.
This fixes the same issue for the binary attributes by adding
them to the properly registered group. As a side effect the
code is further cleaned up.

Our charger manager can optimize the battery capacity periodically, so
we can save last battery capacity into registers. Then next system
power-on, we can read the last saved battery capacity as the initial
battery capacity, which can make the battery capacity more accurate.
