[SCSI] aacraid: add user initiated reset

Browse Source 
Add the ability for an application to issue a hardware reset to the
adapter via sysfs. Typical uses include restarting the adapter after it
has been flashed. Bumped revision number for the driver and added a
feature to periodically check the adapter's health (check_interval),
update the adapter's concept of time (update_interval) and block
checking/resetting of the adapter (check_reset).
