net: tsec: Support <reg> property from the subnode "queue-group"
At present the tsec driver uses a non-standard DT bindings to get its <reg> base / size. The upstream Linux kernel seems to require the <reg> base / size to be put under a subnode of the eTSEC node with a name prefix "queue-group". This is not documented in the kernel DT bindings, but it looks every dtsi file that contains the eTSEC node was written like this. This commit updates the tsec driver to handle this case.
