PCI: rcar-gen2: Use devm_platform_get_and_ioremap_resource()

Convert calls to platform_get_resource() and devm_ioremap_resource()
into a single call to devm_platform_get_and_ioremap_resource(), to
simplify the code.

This new helper added in commit 890cc39a8799 ("drivers: provide
devm_platform_get_and_ioremap_resource()") does what both of the
other separate functions do.
