Revert "power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL"

This reverts commit 8efe444038a205e79b38b7ad03878824901849a8 and
4cbc76eadf56399cd11fb736b33c53aec9caab8c.

Richard@laptop.org was apparently using CAPACITY_LEVEL for debugging
battery/EC problems, and was upset that it was removed.  This readds it.
