Good to have this 'info chardev' support, to avoid need to parse stderr
to try & find PTY device paths :-) 

I don't know if the info is easily available, but for the 'vc' use case,
it might be worth exposing the VC number, so a intelligent client app can
read it, and be able to send 'ctl-alt-NN' in the VNC/SDL console to switch
directly to the char device's VC.
