Applied to pci/misc for v4.3 with changelog as follows. Original patch
touched some code that was removed in v4.2, so I adjusted for that, too.

PCI: Move PCI_FIND_CAP_TTL to pci.h and use it in quirks
Some quirks search for a HyperTransport capability and use a hard-coded TTL
value of 48 to avoid an infinite loop.
Move the definition of PCI_FIND_CAP_TTL to pci.h and use it instead of the
hard-coded TTL values.
