From: Markus Schneider-Pargmann <msp@xxxxxxxxxxxx>

Add logic in order to be able to turn on the control buffer on MT8365.
This change now allows to have control buffer support for MTK_THERMAL_V1,
and it allows to define the register offset, and mask used to enable it.

This change conflicts with commit 4f2ee0aa2e706

I fixed it with:

-       if (mt->conf->version != MTK_THERMAL_V1) {
-               mtk_thermal_turn_on_buffer(apmixed_base);
+       mtk_thermal_turn_on_buffer(apmixed_base);
+
+       if (mt->conf->version != MTK_THERMAL_V1)
                mtk_thermal_release_periodic_ts(mt, auxadc_base);
-       }

Let me know if there is something wrong.
