Add sil_iowrite{8,16,32}() and sil_ioread{8,16}() helpers, then use them to
merge code accessing configuration registers through PCI and MMIO together.

[ because of this SATA initialization bits from setup_mmio_siimage() are
  moved to init_chipset_siimage() ]

This also cuts code size a bit:

   text    data     bss     dec     hex filename
   4437     164       0    4601    11f9 drivers/ide/pci/siimage.o.before
   3979     164       0    4143    102f drivers/ide/pci/siimage.o.after

While at it:

* Use I/O ops directly instead of using ->IN{B,W} and ->OUT{B,W}.

* Fixup CodingStyle in setup_mmio_siimage().

* Rename 'tmpbyte' variable to 'tmp' in init_chipset_siimage().

* Add ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods to

* Cleanup atapi_{in,out}put_bytes().

v2:
* Add 'struct request *rq' argument to ->ata_{in,out}put_data methods
  and don't byte-swap disk fs requests (we shouldn't un-swap fs requests
  because fs itself is stored byte-swapped on the disk) - this is how
  things were done before the patch (ideally device mapper should be
  used instead but it would break existing setups and would have some
  performance impact).

This bug was introduced in the 2.6.24 i386/x86_64 tree merge, where
MSI-X vector allocation will eventually fail.  The cause is the new
bit array tracking used vectors is not getting cleared properly on
IRQ destruction on the 32-bit APIC code.

This can be seen easily using the ixgbe 10 GbE driver on multi-core
systems by simply loading and unloading the driver a few times.
Depending on the number of available vectors on the host system, the
MSI-X allocation will eventually fail, and the driver will only be
able to use legacy interrupts.

I am generating the same patch for both stable trees for 2.6.24 and
2.6.25.

  hrtimer: timeout too long when using HRTIMER_CB_SOFTIRQ

Since both the IDE interface and SMC 91C111 Ethernet chip are on-board
devices, not SOC devices, move the platform device registration form the
common to the board specific code.

While at it, remove semicolon (which didn't break compilation only by
chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming:

- change 'au1200_ide0_' variable name prefix to the mere 'ide_';

- change 'smc91x_' variable name prefix to 'smc91c111_' since that's the
  name of the chip used on the boards;

- drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet
  on-board devices;

- change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of
  the macros describing the Ethernet chip for consistency with the IDE
  macros;

- change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is
  indeed a shift count) in the names of the macros describing the IDE
  interface.
