Add reverse scaling function for PMIC5 Gen2 ADC_TM, to convert
temperature to raw ADC code, for setting thresholds for
thermistor channels.

Instead of custom data type re-use generic struct u32_fract.
No changes intended.

Add support for Thermal Monitoring part of PMIC5. This part is closely
coupled with ADC, using it's channels directly. ADC-TM support
generating interrupts on ADC value crossing low or high voltage bounds,
which is used to support thermal trip points.

qcom_vadc7_scale_hw_calib_die_temp() uses a table format different from
the rest of volt/temp conversion functions in this file. Also the
conversion functions results in non-monothonic values conversion, which
seems wrong.
Rewrite qcom_vadc7_scale_hw_calib_die_temp() to use
qcom_vadc_map_voltage_temp() directly, like the rest of conversion
functions do.

struct vadc_map_pt is not used outside of qcom-vadc-common.c, so move it
there from the global header file.

qcom-vadc-common module will be used by ADC thermal monitoring driver,
so move it to global include dir.
