thermal: mediatek: use of_device_get_match_data()

ryderlee1110 · Eduardo Valentin · commit 9efc58dfa14a · 2018-05-06T16:53:47.000-07:00
The usage of of_device_get_match_data() reduce the code size a bit.

Also, the only way to call mtk_thermal_probe() is to match an entry in
mtk_thermal_of_match[], so of_id cannot be NULL.
