[PATCH v9 10/13] PCI: Give pci_intx() its own devres callback

[Krzysztof Wilczyński]

[...]
> pci_intx() calls into pcim_intx() in managed mode, i.e., when
> pcim_enable_device() had been called. This recursive call causes a bug
> by re-registering the device resource in the release callback.
> 
> This is the same phenomenon that made it necessary to implement some
> functionality a second time, see __pcim_request_region().
> 
> Implement __pcim_intx() to bypass the hybrid nature of pci_intx() on
> driver detach.
