Subject: [v5, 1/1] clocksource/drivers/timer-mediatek: optimize systimer irq clear flow on shutdown

From: "fengquan.chen" <fengquan.chen@...iatek.com>

mtk_syst_clkevt_shutdown is called after irq disabled in suspend flow,
clear any pending systimer irq when shutdown to avoid suspend aborted
due to timer irq pending

Also as for systimer in mediatek socs, there must be firstly enable
timer before clear systimer irq
