PCI: Add pci_find_ht_capability() for finding Hypertransport capabilities
There are already several places in the kernel that want to search a PCI
device for a given Hypertransport capability. Although this is possible
using pci_find_capability() etc., it makes sense to encapsulate that
logic in a helper - pci_find_ht_capability().
To cater for searching exhaustively for a capability, we also provide
pci_find_next_ht_capability().
We also need to cater for the fact that the HT capability fields may be
either 3 or 5 bits wide. pci_find_ht_capability() deals with this for you,
but callers using the #defines directly must handle that themselves.
