855ed4c598 Expand and reorganize the pci(9) manpage a bit:
- Document the following routines: pci_alloc_msi(), pci_alloc_msix(),
  pci_find_cap(), pci_get_max_read_req(), pci_get_vpd_ident(),
  pci_get_vpd_readonly(), pci_msi_count(), pci_msix_count(),
  pci_pending_msix(), pci_release_msi(),  pci_remap_msix(), and
  pci_set_max_read_req().
- Group the functions into five sub-sections: raw configuration access,
  locating devices, device information, device configuration, and
  message signaled interrupts.
- Discourage use of pci_disable_io() and pci_enable_io() in device drivers.
  The PCI bus driver handles this automatically as resources are activated.

adb6390718 Update the documentation on pci_get/set_powerstate(). These methods are
not ACPI-specific at all, but deal with PCI power states.  Also,
pci_set_powerstate() fails with EOPNOTSUPP if a request is made that the
underlying device does not support rather than falling back to somehow
setting D0.

9415d1e0ac Add pci_save_state() and pci_restore_state() wrappers around
pci_cfg_save() and pci_cfg_restore() for device drivers to use when
saving and restoring state (e.g. to handle device-specific resets).

55aaf894e8 Make the PCI code aware of PCI domains (aka PCI segments) so we can
support machines having multiple independently numbered PCI domains
and don't support reenumeration without ambiguity amongst the
devices as seen by the OS and represented by PCI location strings.
This includes introducing a function pci_find_dbsf(9) which works
like pci_find_bsf(9) but additionally takes a domain number argument
and limiting pci_find_bsf(9) to only search devices in domain 0 (the
only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are
changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order
to no longer report false positives when searching for siblings and
dupe devices in the same domain respectively.
Along with this change the sole host-PCI bridge driver converted to
actually make use of PCI domain support is uninorth(4), the others
continue to use domain 0 only for now and need to be converted as
appropriate later on.
Note that this means that the format of the location strings as used
by pciconf(8) has been changed and that consumers of <sys/pciio.h>
potentially need to be recompiled.

aac0aafa05 Bring in a manual page documenting some important functions of the
PCI bus interface.  I have made some modifications to this manual
page, so it looks a bit different from the original version that
was posted to me.
