i2c: i801: Drop two outdated comments

Browse Source 
* Timeouts are reported even in interrupt mode since commit
  b3b8df9772 ("i2c: i801: Use wait_event_timeout to wait for
  interrupts") so drop the comment which claims this only happens in
  polled mode.
* xact does not include the PEC bit, as the driver does not support
  software PEC.
