thermal/drivers/mediatek: Fix control buffer enablement on MT7896
[ Upstream commit 371ed6263e2403068b359f0c07188548c2d70827 ]
Reading thermal sensor on mt7986 devices returns invalid temperature:
bpi-r3 ~ # cat /sys/class/thermal/thermal_zone0/temp
-274000
Fix this by adding missing members in mtk_thermal_data struct which were
used in mtk_thermal_turn_on_buffer after commit 33140e668b10.
