[SCSI] aacraid: SMC vendor identification

Due to an internal limit associated with the AdapterTypeText field,
SMC required a product ID that overloaded the combined vendor and
product ID. A decision was made to ship the SMC products without a
vendor string dropping the defacto space that used to delineate vendor
and product to boot. To correct this, we needed to adjust the code in
the driver to parse out the vendor and product strings for the
adapter. We match of 'AOC' in the AdapterTypeText, if so we set the
vendor to SMC and place the entire AdapterTypeText into the product
field.

This only affects the cosmetic presentation of the Adapter vendor and
product in the logs and in sysfs.
