ENGR00155995 [MX6]Adjust default thermal point
Current thermal reading formula is not accurate,
and different board has different value, previous
setting of trip point setting is too low, and some
boards can reach hot and critical point easily, so
change the trip point as below:
critical : 50 -> 100 C
hot : 40 -> 90 C
active : 30 -> 80 C
these trip points value can also be changed via echo
an value into /sys/class/thermal/thermal_zone0/trip..
