[ide] siimage: fix the various SI3112 hangs

From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
(some changes by me - bart)

The current driver looks at fields before it is safe to, we move the
mod15rm bug handler to be a fixup and this ensures the probe has been
completed before we use the ident data.

<bzolnier@trik.(none)> (04/11/06 1.2473)
[ide] apply undecoded slave fixup only for ide-cs

From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
(some changes by me - bart)

We add probe_hwif_init_with_fixup (seperate naming as requested by
Bartlomiej). This runs a fixup on present interfaces before attaching
the drives. In order to be useful we need also an _with_fixup version
of ide_register_hw function.

The sometimes troublesome undecoded slave detector is moved to its own
function and exported so that ide-cs and the upcoming delkin_cb can both
use it (along with any arch specific cf/pcmcia drivers I don't know
about). The non-relevant checks for this scenario are removed.

[ide] ns87415: small cleanup

ide_hwif_setup_dma() calls pci_set_master() if necessary.
pci_set_master() (indirectly via pcibios_set_master()) sets
PCI_LATENCY_TIMER to a "reasonable" value.

<bzolnier@trik.(none)> (04/11/05 1.2468)
[ide] ns87415: PA-RISC update

From: Grant Grundler <grundler@xxxxxxxxxxxxxxxx>
(minor changes by me - bart)

Move Superio (NatSem 87560) IDE hacks into the ns87415 driver
instead of exporting IDE data structures.

To date, only PA-RISC port is known to use the 87560 chip.
