Philipp Stanner 815a3909ea PCI: Move devres code from pci.c to devres.c ...

The file pci.c is very large and contains a number of devres functions.
These functions should now reside in devres.c.

Move as much devres-specific code from pci.c to devres.c as possible.

There are a few callers left in pci.c that do devres operations. These
should be ported in the future. Add corresponding TODOs.

The reason they are not moved right now in this commit is that PCI's devres
currently implements a sort of "hybrid-mode": pci_request_region(), for
instance, does not have a corresponding pcim_ equivalent, yet. Instead, the
function can be made managed by previously calling pcim_enable_device()
(instead of pci_enable_device()). This makes it unreasonable to move
pci_request_region() to devres.c. Moving the functions would require
changes to PCI's API and is, therefore, left for future work.

In summary, this commit serves as a preparation step for a following
patch series that will cleanly separate the PCI's managed and unmanaged
API.
