[SCSI] aacraid: add new driver features flags
Feature enhancement, adding a 'flags' entry that will reside in the host controller's tree, with a newline separated list of arbitrary ascii named features that indicate whether the combination of driver and controller has support for said feature. Breaking from the one-line output typical of sysfs entries, newline was added to tailor for grep, or simple gets line by line string match within an application. I added one for a compiler time check for existence of debug print output, one for an optional manifest defined enhanced status reporting in the logs, and one for runtime reporting whether the controller and driver supports arrays larger than 2TB. Adaptec's storage management software uses the last flag to determine whether to make available the creation of arrays larger than 2TB, otherwise a warning is posted.
