Subject: [PATCH 199/203] PCI: mvebu: Convert to use devm_ioremap_resource
Commit 75096579c3ac ("lib: devres: Introduce devm_ioremap_resource()")
introduced devm_ioremap_resource() and deprecated the use of
devm_request_and_ioremap().
While at it, modify mvebu_pcie_map_registers() to propagate error code.
