165701d9fc siimage: add sil_* I/O ops
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().

There should be no functional changes caused by this patch.

* 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).

fcbd3b4b92 [MIPS] Pb1200/DBAu1200: move platform code to its proper place
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.

e160124ff6 ide: remove IDE_HFLAG_NO_AUTOTUNE host flag
* Don't set IDE_HFLAG_NO_AUTOTUNE host flag in sgiioc4 and icside
  host drivers - there is no need for it as they don't implement
  ->set_pio_mode method.

* Remove no longer needed IDE_HFLAG_NO_AUTOTUNE host flag.

There should be no functional changes caused by this patch.
