ARM: dts: odroidxu3: adjust thermal trip points

Browse Source 
This change adjusts thermal trip points in order to improve performance.
1. Fan operates the highest speed at 60C (before 70C).
2. CPU thermal-throttlling temperatures are changed to 85C/95C from 70C/85C.
3. CPU thermal-throttling polocy is changed---Lower the BIG cores' clock
first, and then lower the clock togethe after BIG cores' clock are become
same as little cores' clock. This polocy is good for parallel processing
while every cores are busy.
4. swtich alerts to from active cooling to passive cooling.
