The Swarm IDE driver uses a release method which is defined in the driver
itself thus potentially oopsable. The simple fix would be to just leak
the device but this patch goes the full length and moves the entire
handling of the platform device in the platform code and retains only
the platform driver code in drivers/ide/mips/swarm.c.

(http://lkml.org/lkml/2007/7/3/257):
"No the old driver doesn't even do that. It starts up. It spuriously
adjusts some non writable PCI BAR registers, prints a message about
resources being in use already then exits."

These host drivers indirectly depend on CONFIG_IDE_ARCH_OBSOLETE_DEFAULTS=y
which is defined only on alpha, x86, ia64, m32r, mips and ppc32.
Moreover:
- on ia64 there is no ISA
- m32r is too new for VLB
- on ppc32 ISA is available only on PPC_CHRP (no default IDE ports)
and PPC_PREP (marked as BROKEN)
[ the common sense tells me that VLB was only used on x86 but there
are urban legends that one of these host drivers was needed on some
other arch - thus the extra care ]
