[SCSI] SAS: consolidate linkspeed definitions
At the moment we have two separate linkspeed enumerations covering
roughly the same values. This patch consolidates on a single one enum
sas_linkspeed in scsi_transport_sas.h and uses it everywhere in the
aic94xx driver. Eventually I'll get around to removing the duplicated
fields in asd_sas_phy and sas_phy ...
