Change Log:
 
1.    Use dword instead of qword to display the value of Connection
State register for debug purpose.

2.    There are some registers location of AIC94xx chip has been changed
according to the new V28 firmware. The patch has redefined the register
location and provided initialization.

3.    The new sequencer firmware v28 for Aic94xx SAS/SATA Linux open
source device driver can be downloaded from
