Function compute_intercept_slope hardcode the sensor slope to
SLOPE_DEFAULT. Change this and use the default value only if a slope is
not defined. This is needed for tsens VER_0 that has a hardcoded slope
table.

VER_0 is used to describe device based on tsens version before v0.1.
These device are devices based on msm8960 for example apq8064 or
ipq806x. Add support for VER_0 in tsens.c and set the right tsens feat
in tsens-8960.c file.

thermal/drivers/tsens: Add VER_0 tsens version
VER_0 is used to describe device based on tsens version before v0.1.
These device are devices based on msm8960 for example apq8064 or
ipq806x. Add support for VER_0 in tsens.c and set the right tsens feat
in tsens-8960.c file.

Device based on tsens VER_0 contains a hardware bug that results in some
problem with sensor enablement. Sensor id 6-11 can't be enabled
selectively and all of them must be enabled in one step.

Rework calibrate function to use common function. Derive the offset from
a missing hardcoded slope table and the data from the nvmem calib
efuses.
Drop custom get_temp function and use generic api.
