Revert "hvc_console: display printk messages on console."
This reverts commit 361162459f62dc0826b82c9690a741a940f457f0.
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.
