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 would like to keep this error message as is.

Can you specify why? devm_request_and_ioremap() and the new
devm_ioremap_resource() both already output an error message if they
can't request or ioremap the memory region, so all this does is output a
duplicate error message.
