soc/mediatek: Set soc_ops.set_resources as no-op

Without setting the set_resources field for soc_ops, we will get an
error during device initialization:

 [ERROR]  CPU_CLUSTER: 0 missing set_resources

Because the set_resources field is considered mandatory, explicitly set
it as no-op noop_set_resources.
