[PATCH] hvc_console: Separate hvc_console and vio code

[PATCH] hvc_console: Separate hvc_console and vio code

Separate the console setup routines of the hvc_console and the vio layer.

Remove the call to find_init_vty from hvc_console.c.

Fail the setup routine if the console doesn't exist, but register the console
again when the specified channel is instantiated.  This scheme maintains the
print buffer semantics while eliminating callout and call back for the console
code.
