net: ti: icssg: Fix portname buffer overflow

portname consists of dev->parent->name ("icssg0-eth",
"icssg1-eth", or "ethernet") and dev->name is the port node
name ("port@0" or "port@1").  Every board DTS in the repository
produces a string that overflows the buffer:

"icssg1-eth-port@0"  17 chars + NUL = 18 bytes  (AM642 EVM, IoT2050)
"ethernet-port@0"    15 chars + NUL = 16 bytes  (SR-SOM, phyboard)

This commits increases portname to 64 bytes and replaces sprintf
by snprintf so that any future DT node name cannot overflow it
regardless of length.
