dyoung a184f1f486 Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9),
pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match
predicate passed to pciide_compat_intr_establish() should ever modify
their pci_attach_args argument, so make their pci_attach_args arguments
const and deal with the fallout throughout the kernel.

For the most part, these changes add a 'const' where there was no
'const' before, however, some drivers and MD code used to modify
pci_attach_args.  Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
    pci_intr_map() was a leftover from Xen 2.  Probably a bug.  I
    stopped writing it.  I have not tested this change.

siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args.
    Probably a bug.  I use a temporary variable.  I have not tested this
    change.

slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args.
    Probably a bug.  Use a local pci_attach_args.  I have not tested
    this change.

viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the
    caller's pci_attach_args.  Probably a bug.  Make a local copy of the
    caller's pci_attach_args and modify the copy.  I have not tested
    this change.

While I'm here, make pci_mapreg_submap() static.

With these changes in place, I have tested the compilation of these
kernels:

with or without my patches in place:
