kohaku: add TEMP_SENSOR_3 and TEMP_SENSOR_4 to DPTF
The Kohaku V24 schematic adds two additional temperature sensors
to the EC. Add these to the DPTF tables.
Cq-Depend: chromium:1742914
BRANCH=none
BUG=b:138578073
TEST=Rebuild EC and BIOS, look for new thermal sensors in kernel.
1. Build EC
``cd ~/trunk/src/platform/ec``
``make -j BOARD=kohaku``
2. Program EC
``./util/flash_ec --board=kohaku``
3. Reboot device
4. Rebuild BIOS
``cd ~/trunk/src/third_party/coreboot``
``FEATURES="noclean" FW_NAME=kohaku emerge-hatch chromeos-ec depthcharge
vboot_reference libpayload coreboot-private-files intel-cmlfsp
coreboot-private-files-hatch coreboot chromeos-bootimage``
5. Use flashrom to program the BIOS
6. Reboot device
7. Log into the root console (ctrl-alt-F2 or servo)
8. Example thermal sensor information
``grep . /sys/class/thermal/t*/type``
Look for "TSR0" through "TSR3" in the output.
