zephyr: add shim thermal support
Add thermal support to Zephyr which includes handling temperature
threshold for certain events. The thresholds are defined in the dts
file as temperature sensor parameters - there are limits per
temperature sensor. The struct ec_thermal_config thermal_params[] array
with all parameters is generated automatically based on
named_temp_sensors node.
Enable "thermalget" and "thermalset" console commands along with
EC_CMD_THERMAL_GET_THRESHOLD and EC_CMD_THERMAL_SET_THRESHOLD host
commands.
Also, add a few functions to utils needed to verify if an event
occurred (falling/rising edge).
BUG=b:179886912
BRANCH=none
TEST=build Zephyr
TEST=Run "thermalget" command to check current thresholds.
Change the thresholds with "thermalset" to verify if AP throttling
is requested.
