driver: thermal: Configure ARM threshold instead of low

Browse source 
LMH DCVSh will retain the mitigation till it clears the Low
threshold. With mitigation happening at 95C, configuring the
low threshold as 65C will hold the mitigation till it clears 65C,
which will impact the performance.

Instead of configuring the low threshold, configure the ARM threshold
from HLOS and low threshold will be configured 2C less than the
high threshold in the trust zone.
