[ide] siimage: fix the various SI3112 hangs
From: Alan Cox <[email protected]>
(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.

[ide] apply undecoded slave fixup only for ide-cs
From: Alan Cox <[email protected]>
(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.

[ide] ns87415: PA-RISC update
From: Grant Grundler <[email protected]>
(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.
