Remove the busproc from pdc202xx_old.c because:

- it handles the obsolete HDIO_TRISTATE_HWIF ioctl instead of the modern
  HDIO_SET_BUSSTATE, so treats its argument wrong;

- I don't think that tristating both channels is good idea (probably can't
  be done otherwise since there seems to be only single bit controlling this).

This patch fixes a bug in sgiioc4 where it was using the default IDE port
I/O operations instead of MMIO.

The IDE part of the IOC4 chip uses MMIO to map the chip registers.
Unfortunately, the sgiioc4 driver uses the default port IO operations,
which happens to have worked for the past few years.  That's about to
change, however, thus this change from inX/outX to readX/writeX.

Some quick backport bits from the libata PATA work to fix things found in
the sis driver.  The piix driver needs some fixes too but those are way to
large and need someone working on old IDE with time to do them.

This patch fixes the case where random bits get loaded into SIS timing
registers according to the description of the correct behaviour from
Vojtech Pavlik.  It also adds the SiS5517 ATA16 chipset which is not
currently supported by the driver.  Thanks to Conrad Harriss for loaning me
the machine with the 5517 chipset.

This removes statically assigned platform numbers and reworks the
powerpc platform probe code to use a better mechanism.  With this,
board support files can simply declare a new machine type with a
macro, and implement a probe() function that uses the flattened
device-tree to detect if they apply for a given machine.

We now have a machine_is() macro that replaces the comparisons of
_machine with the various PLATFORM_* constants.  This commit also
changes various drivers to use the new macro instead of looking at
_machine.

I just purchased a HighPoint Rocket 1520 SATA controller.  There seems to
be no libata driver (yet), but there is an ide driver, hpt366.  When the
driver gets loaded, it causes a kernel NULL pointer dereference in
pci_bus_clock_list.  It seems to be because the driver is waiting for clock
stabilization in init_hpt37x() which never comes.  The driver just
continues on with the pci drvdata set to NULL, instead of a valid clock
entry.  The following patch prevents the NULL dereference from happening,
but instead exit with an error.
