It's plain wrong for PCMCIA to select HAVE_IDE that implies e.g. the
availability of an asm/ide.h
It turns out this was done for ARM, and we can simply always select
HAVE_IDE on ARM instead of manually tracking which platforms might
possible have an IDE controller directly or indirectly.

ETRAX_IDE was marked as broken last year with the comment
"it doesn't even compile currently".
Remove it since it won't get fixed in the near future.

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
falconide and q40ide host drivers (->ata_* methods are implemented on
top of ->atapi_* methods so they also do byte-swapping now).
* 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).

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.
