[ide] remove needless exports from ide-taskfile.c

Also remove unused MAX_DMA define.

Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

<bzolnier@trik.(none)> (04/10/26 1.2195)
[ide] add ide_use_dma()

Should prevent bugs like the recent piix one in the future.

[ide] add pci_get_legacy_ide_irq()

This patch adds pci_get_legacy_ide_irq() to the PCI layer for dealing
with PCI IDE chipsets that use the "legacy mode" IRQ routing, thus
violating the normal PCI routing. The generic implementation provides
IRQ numbers 14 and 15, and it adds a ppc64 specific one with platform
callbacks so that a plaform can provide different IRQ numbers for "legacy"
IDE. I only fixed the amd7xxx.c driver for now, I expect people using
this interface will slowly fix their drivers (I will fix via soon as I'll
need it too, and maybe a few others).

[ide] remove unused internal exports from ide core

From: Arjan van de Ven <arjan@fenrus.demon.nl>

ide-iops.c exports a few functions that either have no users or have no
users AND shouldn't be used by drivers; the patch below unexports them.

-EXPORT_SYMBOL(SELECT_INTERRUPT);
-EXPORT_SYMBOL(SELECT_MASK);
-EXPORT_SYMBOL(QUIRK_LIST);
-EXPORT_SYMBOL(ata_vlb_sync);

only used in the core ide code

-EXPORT_SYMBOL(ata_input_data);
-EXPORT_SYMBOL(ata_output_data);

drivers should (and do) use the hwif-> function pointer variant of these,
these functions are internal and used for setting the default hwif->
function pointers only. No need to export, in fact exporting is only asking
for accidents

[ide] ide-probe: undecoded slave fixup

Undecoded slave fixup is a oneliner patch to ide-probe to
recognize both of my Maxtor drives that appear to have the same
serial number, D3000000.
