Pull CalWakeUp until Startup Handshake

The FETK has the ability to wake up the ECU by applying voltage to the Cal-
WakeUp pin of the ECU connector. This allows the FETK to configure a mea-
surement while the ECU is off.
When waking up the ECU via the CalWakeUp pin, it can be configured if the pin
is driven high until the microcontroller core voltage (VDDP) is high or if the pin
should be driven high until the start-up handshake between ECU and FETK is
complete.
