arm64: remove printk() before console_init()
printk() shouldn't be called until the consoles have been
initialized. This just so happened to work by luck. Once
CONFIG_SMP is enabled that breaks because of spinlock
usage in uncached memory.
BUG=chrome-os-partner:31761
BRANCH=None
TEST=Built with CONFIG_SMP and ramstage doesn't hang early.
