tpacpi_driver_event() already only responds to hkey events which it knows
about. Make it return a bool and return true when it has handled the event.
This avoids the need to list TP_HKEY_EV_foo values to which it responds
both in its caller and in the function itself.
Instead callers can now call it unconditionally and check the return value.
