net: ti: am65-cpsw: Fix buffer overflow
The device name is a concatenation of the device node name of the cpsw
device and of the device node name of the port. In my case that is
ethernet@8000000
port@1
First the buffer is really too small, but more importantly, there is no
boundary check. Use snprintf() and increase the buffer size.
