To simplify the calling sequence for mtk_wdt_preinit() and we always
adjust request setting in mtk_wdt_preinit(), we rename
mtk_wdt_preinit() to mtk_wdt_set_req() and call it in mtk_wdt_init().
From this modification, we can also enable thermal hardware reset
feature (CB:64676, CB:64675) in MT8192 and MT8195.

Under the current watchdog setting, the system will not reboot when the
temperature is too high. To enable thermal hardware reset, we need to
enable thermal control request and set it to reboot mode.
Note that because thermal throttle (by lowering cpu frequency) is
currently enabled, the thermal hardware reset shouldn't be triggered
under normal circumstances.
This feature is only for new hardware structure for thermal. Therefore,
we only need to apply it on MT8192/MT8195/MT8186.
This setting is based on thermal and watchdog section of MT8192
Function Specification.
