serial8250: Mark console as CON_ANYTIME

Browse Source 
While trying to debug a cpu-hotplug issue I noticed printk() stopped
working once the cpu got marked offline, since the 8250 serial console
doesn't have any per-cpu resources the CON_ANYTIME bit is the safe and
documented way to make it work again.
