[PATCH] i2c: i801: Drop two outdated comments

[Jean Delvare <jdelvare@suse.de>]

* Timeouts are reported even in interrupt mode since commit
  b3b8df97723d ("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.
