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.
