thermal/drivers/mediatek: Use devm_of_iomap to avoid resource leak in mtk_thermal_probe
Smatch reports:
1. mtk_thermal_probe() warn: 'apmixed_base' from of_iomap() not released.
2. mtk_thermal_probe() warn: 'auxadc_base' from of_iomap() not released.
The original code forgets to release iomap resource when handling errors,
fix it by switch to devm_of_iomap.
