Documentation: devres: fix error about PCI devres
The documentation states that pcim_enable_device() will make "all PCI
ops" managed. This is totally false, only a small subset of PCI
functions become managed that way. Implicating otherwise has caused at
least one bug so far, namely in commit 8558de401b5f ("drm/vboxvideo: use
managed pci functions").
Change the function summary so the functions dangerous behavior becomes
obvious.
