* initial changes for the gammaturbo bringup * added preliminary TPS546 changes * added preliminary EMC2103 support * ASIC temp seems to be maybe working. * magically now fan seems to have the right polarity * added in ideality and beta constants (currently unused). Fixed EMC2103_get_fan_speed() * abstract fan and ASIC temp into thermal functions * abstracted voltage regulator specifics out of tasks and into power.c and vcore.c functions * add TPS546 support for multiple models * move TPS40305/DS4432U vout setter to DS4432U.c * move all ASIC specific functions to asic.c * bad device_model nvs handling * remove old code * add workaround for TPS546 VIN_UV_WARN_LIMIT silicon bug.
