thermal/drivers/tsens: limit num_sensors to 9 for msm8939

[ Upstream commit 903238a33c116edf5f64f7a3fd246e6169cccfa6 ]

On msm8939 last (hwid=10) sensor was added in the hw revision 3.0.
Calibration data for it was placed outside of the main calibration data
blob, so it is not accessible by the current blob-parsing code.

Moreover data for the sensor's p2 is not contiguous in the fuses. This
makes it hard to use nvmem_cell API to parse calibration data in a
generic way.

Since the sensor doesn't seem to be actually used by the existing
hardware, disable the sensor for now.

Fixes: 332bc8ebab2c ("thermal: qcom: tsens-v0_1: Add support for MSM8939")
