usb-dbg: Support sensor out of threshold message present

Description:
 - Modified sensors config for greatlakes platform those currently supported.
 - Support OCP debug card sensor frame threshold message shown when sensor value is out of threshold.
   e.g “P0_temp XXC/UCR”
 - Support OCP debug card screen blink and invert the color if the sensor out of threshold.

Test Case:
Sensor threshold message should be shown on debug card when the sensor value is out of threshold.
