platform/x86: ideapad-laptop: Support multiple power_supply_ext definitions

Some recent devices supports more charge_types. To properly support
these device without breaking the existing ones, we need to define
multiple power_supply_ext for different GBMD/SBMC interface revisions.

No functional change intended.
