Up to now the MAPD's ITT size field has been ignored. It encodes the number of eventid bit minus 1. It should be used to check the eventid when a MAPTI command is issued on a device. Let's store the number of eventid bits in the its_device and do the check on MAPTI. Also make sure the ITT size field does not exceed the GITS_TYPER IDBITS field.
