Disable Virtual DMA support for now (it causes system hangs).
Thanks to TAKADA Yoshihito for the help with debugging the problem.

We don't need init_hwif_ali15x3() on the PowerPC systems either.
Before:
ALI15X3: IDE controller (0x10b9:0x5229 rev 0xc8) at PCI slot 0001:03:1f.0
ALI15X3: 100% native mode on irq 19
ide0: BM-DMA at 0x1120-0x1127
ide1: BM-DMA at 0x1128-0x112f
hda: SONY DVD RW AW-Q170A, ATAPI CD/DVD-ROM drive
hda: UDMA/66 mode selected
ide0: Disabled unable to get IRQ 14.
ide0: failed to initialize IDE interface
ide1: Disabled unable to get IRQ 15.
ide1: failed to initialize IDE interface
After:
ALI15X3: IDE controller (0x10b9:0x5229 rev 0xc8) at PCI slot 0001:03:1f.0
ALI15X3: 100% native mode on irq 19
ide0: BM-DMA at 0x1120-0x1127
ide1: BM-DMA at 0x1128-0x112f
hda: SONY DVD RW AW-Q170A, ATAPI CD/DVD-ROM drive
hda: UDMA/66 mode selected
ide0 at 0x1100-0x1107,0x110a on irq 19
ide1 at 0x1110-0x1117,0x111a on irq 19
hda: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache
ide0 works well, though I can't test ide1, it isn't traced out on
the board.

Some change to the IDE layer are causing the siimage driver to crash
at boot with a NULL dereference. This is due to the sil_dma_ops not
containing all the necessary pointers. I suppose it used to just
"override" the defaults while now, it needs to contain everything.
[bart: while at it: sil_dma_ops should be const now (pointed out by Sergei)]

Fix 18 errors and several warnings given by checkpatch.pl:
- use of C99 // comments;
- trailing whitespace;
- 'switch' and 'case' not at the same indentation level;
- no space before the open parenthesis of the 'if' and 'switch' statements;
- space between function name and open parenthesis (though I have introduced
such warnins in some places since the code looks prettier with the spaces);
- including <asm/io.h> instead of <linux/io.h>;
- line over 80 characters.
In addition to these changes, also do the following:
- make the arrays in sil_set_pio_mode() 'static', and make the arrays in
sil_set_dma_mode() 'static const';
- change the string of the 'if' statements into the 'switch' statement in
sil_pata_udma_filter();
- drop the needless '==' operators from the 'if' statements where a condition
is a mere bit test;
- remove needless initializer for the 'tmp' variable in init_chipset_siimage();
- beautify groups of the variable initializers and assignment operators;
- add new line after variable definitions;
- remove new line between the comment and the statements it refers to;
- remove needless curly braces and parentheses;
- fix typos, capitalize acronyms, etc. in the comments...

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().
