device: Add pciexp_find_next_extended_cap function
Some PCIe devices have extended capability lists that contain
multiples instances of the same capability. This patch provides a
function similar to pciexp_find_extended_cap that can be used to
search through multiple instances of the same capability by returning
the offset of the next extended capability of the given type following
the passed-in offset. The base functionality of searching for a given
capability from an offset is extracted to a local helper function and
both pciexp_find_extended_cap and pciexp_find_next_extended_cap use
this helper.
