[POWERPC] Register udbg console early on pseries LPAR
On pseries LPAR we can call the udbg routines, and the udbg console very early. So mark the udbg console as safe to call early in boot, and register the udbg console as soon as the udbg routines are hooked up. This allows platforms/pseries code to use printk() and pr_debug() rather than needing to call udbg_printf() directly for early debugging. This is nice because a) it's standard, b) it goes via the printk buffer, and c) you can get printk time stamps.
