Subject: [PATCH v2 2/3] clocksource: mtk_timer: fix pr_warn() messages in mtk_timer_init

1) Change pr_warn()s to pr_err()s. These messages are actually
errors and not warnings.
2) Add missing \n.
3) Error message for kzalloc() failure is removed per suggestion
by Joe Perches. There is generic stack_dump() for allocation issues.
