can: ti_hecc: convert to devm_platform_ioremap_resource_byname()
Use the function devm_platform_ioremap_resource_byname() to simplify source code which calls the functions platform_get_resource_byname() and devm_ioremap_resource(). Remove also a few error messages which became unnecessary with this software refactoring.
