net: xilinx: axienet: Use devres for resource management in probe path

Transition axienet_probe() to managed resource allocation using devm_*
APIs for network device and clock handling, while improving error paths
with dev_err_probe(). This eliminates the need for manual resource
cleanup during probe failures and streamlines the remove() function.
