Revert "eSEL: Remove unused code related to logging eSEL"

This reverts commit 54fad6de0541c2f98e9b511f1d30bbcbcd743db6.

This commit is reverted because the mapping of D-Bus object path to
sensor information is still needed. The mapping is needed to serve
the SEL commands which translate D-Bus logging objects to SEL entries.
