The 'name' field is common to all ports, so it makes sense to put it in
the VirtIOSerialPort struct. (Internal users can pre-define it to their
liking, eg, org.qemu.vnc)

The console init function has extra init'ing to do, like disable buffer
caching, set is_console to true, etc., so there are two init fns.
