thermal/drivers/mediatek: Use devm_of_iomap to avoid resource leak in mtk_thermal_probe

[ Upstream commit f05c7b7d ]

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.
