MT6873/MT6753/MT6885 如何设定battery的固定温度？

[DESCRIPTION]

项目前期，可能battery没有ready，会报battery thermal关机，导致手机开不起来。

[sys.powerctl]=[shutdown,thermal,battery]

[SOLUTION]

参考如下临时patch，将battery温度固定在25度。

1. diff --git a/drivers/power/supply/mediatek/battery/mtk_battery.c b/drivers/power/supply/mediatek/battery/mtk_battery.c
