[PATCH 1/2] PCI: Make pcim_request_region() a public function

pcim_request_region() is the managed counterpart of
pci_request_region(). It is currently only used internally for PCI.

It can be useful for a number of drivers and exporting it is a step
towards deprecating more complicated functions.

Make pcim_request_region a public function.
