thermal/drivers/qcom/tsens-v0_1: Fix mdm9607 slope values
[ Upstream commit 6812d1dfbca99cd5032683354bf50e0002b2aa02 ]
According to the msm-3.18 vendor kernel from Qualcomm [1], mdm9607 uses
a non-standard slope value of 3000 (instead of 3200) for all sensors.
Fill it properly similar to the 8939 code added recently.
