This patch adds the PCI ID definitions for new adapters based on the next
generation 64 bit IOA PCI interface chip.  New entries have been added to the
ipr_pci_table[] array for the adapters and to the ipr_chip[] array for the new
versions of the chip.

Older entries have been removed for cards that did not ship.

This patch adds a reboot notifier that will issue a shutdown prepare command
to all adapters.  This helps to prevent a problem where the primary adapter can
get shut down before the secondary adapter and cause the secondary adapter to
fail over and log and error.
This patch also removes the "enable_cache" paramater as it is obsolete.  Write
cache for an adapter is now controlled from the iprconfig utility.

When writing a disc on certain lite-on dvd-writers (also rebadged
as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends
up in the datastream and on the disc, causing silent corruption.
Delaying between sending the CDB and starting DMA seems to
prevent this.

I do not know if there are burners that do not suffer from
this, but the patch should be safe for those as well.

There are many reports of this issue, but AFAICT no solution was
found before. For example:

I have a Delkin Devices compact flash card that isn't being recognized using the
SATA/PATA drivers.
The card is recognized and works with the deprecated ATA drivers.

The error I am seeing is:
ata1.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0)

I tracked it down to ata_id_is_cfa() in include/linux/ata.h.
The Delkin card has id[0] set to 0x844a and id[83] set to 0.
This isn't what the kernel expects and is probably incorrect.

The simplest work-around is to add a check for 0x844a to ata_id_is_cfa().
