add platform specific callout functions for FSP integration.

Make the HWAS function processCallout() be common instead of hostboot
specific, and create new platform specific functions for the processing
of procedure and hardware callouts. Intention is that hostboot and fsp
will use these to read the hwas hostboot-created callout_ud_t structure
out of an errlog.
