[media] soc_camera/sh_mobile_csi2: Convert to devm_ioremap_resource() 



Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() 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.
