zephyr: Add PLATFORM_EC_MAX_SENSOR_FREQ_MILLIHZ
By default, maximal sensor ODR are capped at 250Mhz.
However, some EC are too slow and can missed samples, failing CTS test.
Add a variable to reduce the maximal ODR allowed.
This variable sets CONFIG_EC_MAX_SENSOR_FREQ_MILLIHZ.
BUG=b:206571439
BRANCH=none
TEST=Check in loop that all samples are timestamp properly:
while true ; do
tast run localhost:22552 hardware.SensorIioserviceHard
sleep 1
done
