[PATCH v6 01/10] PCI: Make pcim_request_all_regions() a public function

[Philipp Stanner <pstanner@xxxxxxxxxx>]

In order to remove the deprecated function
pcim_iomap_regions_request_all(), a few drivers need an interface to
request all BARs a PCI device offers.

Make pcim_request_all_regions() a public interface.
