John Baldwin c668000b69 Expand the set of APIs available for locating PCI capabilities:
- pci_find_extcap() is repurposed to be used for fetching PCI-express
  extended capabilities (PCIZ_* constants in <dev/pci/pcireg.h>).
- pci_find_htcap() can be used to locate a specific HyperTransport
  capability (PCIM_HTCAP_* constants in <dev/pci/pcireg.h>).
- Cache the starting location of the PCI-express capability for PCI-express
  devices in PCI device ivars.
