Subject: [PATCH v5 0/6] thermal: tegra: add SOCTHERM support for Tegra114

SOCTHERM is thermal sensor and thermal throttling controller found in Tegra
SoC starting from Tegra114. Existing Tegra124 setup is mostly compatible
with Tegra114 and needs only a few slight adjustmets of fuse calibration
process.

Changes in v2:
- no changes, resend.

Changes in v3:
- expanded desciption of "thermal: tegra: soctherm-fuse: parametrize
  configuration further" commit
- changes title of "thermal: tegra: soctherm-fuse: parametrize
  configuration further" to "thermal: tegra: soctherm-fuse: prepare
  calibration for Tegra114 support"
- Tegra11x > Tegra114 and Tegra12x > Tegra124
- ft and cp shift bits dropped
- clarified tegra114 precision
- lower_precision > use_lower_precision
- nominal calibration ft and cp hardcoded into SoC specific structures
- added tegra114-soctherm header into dt-bindings

Changes in v4:
- fixed Tegra124/132/210 cp mask
- dropped TEGRA114_SOCTHERM_SENSOR_NUM from header
- TEGRA_SOCTHERM_THROT_LEVEL_ made SoC specific
- adjusted soctherm node and inclusions in tegra114.dtsi
- dropped use_lower_presision and nominal_calib_cp options

Changes in v5:
- fixed CPU and GPU hotspot offset values
- added static_assert()s to assert the TEGRA114_* and TEGRA124_*
  counterparts are equal
