* PA14 is a pull up pin. But, some V5 boards it start with LOW state! And just behave properly when the Z- PROBE is actived at least once.
* So, if the sensor isnt actived, the PA14 pin will be forever in LOW state, telling Marlin the probe IS ALWAYS ACTIVE, that isnt the case!
* Chitu original firmware seems to start with every pullup PIN with HIGH to workaround this.
* So we are doing the same here.
* This hack only works if applied *before* the GPIO Init, it's the reason I did it here.
