Subject: [PATCH] pci: use newly introduced devm_ioremap_resource()

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

I think the idea was to combine changes to the 2 files in one patch.
Then the subject will truly reflect what it's doing...
