mediatek/mt8183: Add watchdog timer support

Using common watchdog timer (WDT) code for reset. Set up watchdog timer
in mtk_wdt_init() to get reset status and disable auto-reboot. Link
common do_hard_reset() to support hard reset.

BUG=b:80501386
BRANCH=none
TEST=both mtk_wdt_init() and do_hard_reset() work on Kukui.
