Revert "hvc_console: display printk messages on console."
This reverts commit 36116245 . It causes an infinite loop when booting Linux under Xen, as so: [ 2.382984] console [hvc0] enabled [ 2.382984] console [hvc0] enabled [ 2.382984] console [hvc0] enabled ... as reported by Konrad Rzeszutek Wilk. And Rusty reports the same for lguest. He goes on to say: "This is not a concurrency problem: the issue seems to be that calling register_console() twice on the same struct console is a bad idea." and Greg says he'll fix it up properly at some point later. Revert for now.
