Subject: [PATCH] watchdog: Kconfig: enable MTK watchdog

Enable CONFIG_MEDIATEK_WATCHDOG when ARCH_MEDIATEK is enabled.

On some platforms (e.g. mt8183-pumpkin), watchdog is enabled by
bootloader, so kernel driver needs to be enabled to avoid watchdog
firing and causing reboot part way through kernel boot.
