[PATCH] v3: fix initial printk buffer address initialization

[Carl-Daniel Hailfinger]

Fix initial printk buffer address initialization. This was broken in
r785 (move from explicit asm to implicit C) and unfortunately qemu never
triggered the bug, only real hardware did.

Thanks to Ron for bisecting this.

Not yet tested but it can't make it worse :-)
