net: ethernet: natsemi: Use pure PCI devres API

The currently used function pci_request_regions() is one of the
problematic "hybrid devres" PCI functions, which are sometimes managed
through devres, and sometimes not (depending on whether
pci_enable_device() or pcim_enable_device() has been called before).

The PCI subsystem wants to remove this behavior and, therefore, needs to
port all users to functions that don't have this problem.

Replace pci_request_regions() with pcim_request_all_regions().
