Only need to pass a cy_softc * to cy_attach().

Clean up the PCI attachment a bit, and adjust the other pieces
to suit.

Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

* Support (not so) new cards. (only Cyclom-8YsP+ is tested)
* Make compilable with CY_DEBUG.

Nuke __BROKEN_INDIRECT_CONFIG.

Change expected mapping register type argument for the pci_mapreg_map()
call for the board's memory space to be PCI_MAPREG_MEM_TYPE_32BIT_1M or
PCI_MAPREG_MEM_TYPE_32BIT depending on the board ID. Also, remove a
bogus extra argument to an interrupt-establishment-error printf. Problems
pointed out by Jarkko Torppa <torppa@cute.fi> in PR 3753, but fixed slightly
differently than he suggested.

rename pci_map_register to pci_mapreg_map. The latter name is more
descriptive, and allows for a sane name for a function which just digs
the info out of the mapping register but doesn't do the mapping.

use pci_map_register(). Also, almost a complete rewrite/cleanup of this
code. (It still needs more!)

New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
devices. It's all "bus space" now, and space tags
differentiate the space with finer grain than the
bus chipset tag.
- Add memory barrier methods.
- Implement space alloc/free methods.
- Implement region read/write methods (like memcpy to/from
bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

backout kprintf changes

- printf -> kprintf, sprintf -> ksprintf
- remove unused variables.
- fix cleanup code in case of probe failure.

New cyclades driver from Timo Rossi.
