Get rid of T124-specific PDIV/HOTSPOT hack.
tegra-soctherm.c contained a hack to set the SENSOR_PDIV and
SENSOR_HOTSPOT_OFFSET registers - it just did two writes of
T124-specific opaque values. Convert these into a form that can be
substituted on a per-chip basis, and into structure fields that have
at least some independent meaning.
