net: dsa: mv88e6xxx: Prevent truncation of longer interrupt names
When adding support for unique interrupt names, after testing on a few
devices, it was assumed 32 characters would be sufficient. This
assumption turned out to be incorrect, ZII RDU2 for example uses a
device base name of mv88e6xxx-30be0000.ethernet-1:0, leaving no space
for post fixes such as -g1-atu-prob and -watchdog. The names then
become identical, defeating the point of the patch.
Increase the length of the string to 64 charactoes.
