pm80xx: add support for ATTO devices during SAS address initiailization

Browse Source 
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.
