drivers/video/exynos/exynos_mipi_dsi.c: 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.
