This patch lays the groundwork for supporting the new HBA-1000 controller
family.A new INIT structure INIT_STRUCT_8 has been added which allows for a
variable size for MSI-x vectors among other things, and is used for both
Series-8, HBA-1000 and SmartIOC-2000.

This patch adds a new functions that periodically sync the time of host
to the adapter. In addition also informs the adapter that the driver is
alive and kicking. Only applicable to the HBA1000 and SMARTIOC2000.

This patch adds support to retrieve the unique identifier data (VPD page
83 type3) for Logical drives created on SmartIOC 2000 products. In
addition added a sysfs device structure to expose the id information.
