[PATCH] cciss: add struct pci_driver shutdown support (replaces reboot notifier)

This patch adds support for the struct pci_driver shutdown method to cciss.
 We require notification of an impending reboot or shutdown so that we can
flush the battery backed write cache (BBWC) on the Smart Array controller.
