c8a35368a7 Replace the hooribly overloaded use of pci_enumerate_bus() - to find out 
the chipset revision - by pci_find_device().
While the latter isn't better technically (works around the otherwise
hierarchical device tree), using it doesn't require PCI configuration
functions to support stuff which philosophically doesn't belong there.
So we get the hands free to restructure things for better loadable
driver support.
(Actually, since this is about chipset internal IDE interfaces where
the PCI device/function numbers are well known, this all is unnecessary.)

f0816e2b90 Enable ATA-133 for AMD8111. From Nicolas Joly in kern/24729. 
pciide_apollo_reg.h already contains the Ultra133 timming values for amd.

6242a54566 There are some cards that map the ATA control and IDE DMA registers 
in a different fashion. Individually, they have the same functionality,
but their layout is different. An example of such a chipset is
the Promise 203xx.

To be able to deal with this, transform the cmd and dma bus_space handles
into an array of handles, each seperately created with bus_space_subregion.
The code generated by using the extra indirection shouldn't change much,
since the extra indirection is negated by having the offset calculation
already done in bus_space_subregion. E.g.

	bus_space_write_4(tag, handle, offset, value)

becomes

	bus_space_write_4(tag, handles[offset], 0, value)

Reviewed by Manuel Bouyer. Tested on wdc_isa, wdc_pcmcia, viaide, piixide (i386)
and on cmdide (sparc64).

a480189bf8 Remove IDE_PCI_CLASS_OVERRIDE -- it wasn't actually used anywhere. In lieu of 
it, add a class/subclass check to drivers that do not (appear) to have a unique
ID for the IDE controller.  This includes aceride, cypide and optiide.

b4c1912d80 * match the nForce3 controller 
* search the whole current PCI bus for the VIA bridge, can't rely on
  it to be function 0 of the same device

36e9866d7b Cosmetic changes: 
- Use static to unexport symbols that don't need to be exported.
- ANSI'ify.
- Some whitespace nits.

9d02ccdbdf Split pciide in per-chip family driver, as proposed in 
http://mail-index.netbsd.org/tech-kern/2003/09/25/0007.html
We now have:
acardide*       at pci? dev ? function ?        # Acard IDE controllers
aceride*        at pci? dev ? function ?        # Acer Lab IDE controllers
cmdide*         at pci? dev ? function ?        # CMD tech IDE controllers
cypide*         at pci? dev ? function ?        # Cypress IDE controllers
hptide*         at pci? dev ? function ?        # Triones/HighPoint IDE controllers

piixide*        at pci? dev ? function ?        # Intel IDE controllers

pciide*         at pci? dev ? function ? flags 0x0000   # GENERIC pciide driver

serverworks driver not commited yet; there are still copyright issues about
it.
