Before commit 622b520f, index=12 meant bus=1,unit=5.
Since the commit, it means bus=0,unit=12. The drive is created, but
not the guest device. That's because the controllers we use with
if=scsi drives (lsi53c895a and esp) support only 7 units, and
scsi_bus_legacy_handle_cmdline() ignores drives with unit numbers
exceeding that limit.
Changing the mapping of index to bus, unit is a regression. Breaking
-drive invocations that used to work just makes it worse.
Revert the part of commit 622b520f that causes this, and clean up
some.
Note that the fix only affects if=scsi. You can still put more than 7
units on a SCSI bus with -device & friends.

The len and is_write arguments to cpu_physical_memory_unmap() were
swapped. This patch changes calls to use the correct argument ordering.

Avoid these warnings with GCC 4.6.0:
/src/qemu/hw/ide/ahci.c: In function 'ahci_reset_port':
/src/qemu/hw/ide/ahci.c:810:14: error: variable 'tfd' set but not used [-Werror=unused-but-set-variable]
/src/qemu/hw/ide/ahci.c: In function 'handle_cmd':
/src/qemu/hw/ide/ahci.c:1103:19: error: variable 'pr' set but not used [-Werror=unused-but-set-variable]
In the tfd variable case, fix the logic also.

This patch adds an emulation layer for an ICH-9 AHCI controller. For now
this controller does not do IDE legacy emulation. It is a pure AHCI controller.
