Subject: [PATCH v4 2/6] thermal: qcom: tsens-v0_1: Fix mdm9607 slope values

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.

Fixes: a2149ab815fc ("thermal/drivers/qcom/tsens-v0_1: Add support for MDM9607")
