arm: mediatek: remove arch_misc_init

The watchdog of mediatek chips is enabled by bootrom before u-boot is
running. Previously we choose to enable the wdt driver only to disable the
watchdog hardware.

Now wdt service is enabled by default. The function arch_misc_init which is
only used to disable wdt is no longer needed.
