qmp/hmp: add rocker device support
Add QMP/HMP support for rocker devices. This is mostly for debugging purposes
to see inside the device's tables and port configurations. Some examples:
(qemu) info rocker sw1
name: sw1
id: 0x0000013512005452
ports: 4
(qemu) info rocker-ports sw1
ena/ speed/ auto
port link duplex neg?
sw1.1 up 10G FD No
sw1.2 up 10G FD No
sw1.3 !ena 10G FD No
sw1.4 !ena 10G FD No
(qemu) info rocker-of-dpa-flows sw1
