Revert "pcidev: remove pcidev_getdevfn() function"

As Edward pointed out correctly this function does more than abstracting
the different versions of `pci_get_dev()`. It also hide the usage of
the global `struct pci_access pacc` from the caller.

This reverts commit 0e8902f1ff2b927bb91a5e89e4fde3d8d71f6692.
