The format of tpdm's peripheral id is 1f0exx. To avoid potential
conflicts in the future, update the .id_table's id to 0x001f0e00.
This update will narrow down the matching range and prevent incorrect
matches. For example, another component's peripheral id might be
f0e00, which would incorrectly match the old id.
