hvc_console: display printk messages on console.
printk only works for "registered consoles." Currently, the hvc_console
code calls register_console() from hvc_instantiate(), but that's only
used in the early console case. In hvc_alloc(), register_console() was
not called.
Add a call to register_console() in hvc_alloc(), set up the index in
the hvc_console, and set up the necessary vtermnos[] and cons_op[]
entries so that printk functions work.
