thermal: qoriq: Use devm_platform_ioremap_resource() instead of of_iomap()
Use devm_platform_ioremap_resource() instead of of_iomap() to save the iounmap() call in error handle path; Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Reviewed-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
