PCI: Make pcim_request_all_regions() a public function

Browse Source 
[ Upstream commit d9d959c36bec59f11c0eb6b5308729e3c4901b5e ]

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.
