pm80xx: add support for ATTO devices during SAS address initiailization
ATTO SAS controllers retrieve the SAS address from the NVRAM in a location different from non-ATTO PMC Sierra SAS controllers. This patch makes the necessary adjustments in order to retrieve the SAS address on these types of adapters.
