Just out of curiosity: is there any reason why this driver needs to
reimplement this? Couldn't this be made to work using the standard
pci_find_next_capability() function?

Other than that it might be a good idea to split this into two patches,
one that moves the existing functionality to the common code and another
that adds the extra functionality.
