Work with MKS PWC——power off when printing finish

Just config in the Marlin source, you need to add code to the pin file of the motherboard used. Take sgen_L V1.0 as an example, find pins_MKS_SGEN_L.h in the marlin firmware, and then add the following code:

#define SUICIDE_PIN P1_23 //Power failure detection pin configuration

#define SUICIDE_PIN_INVERTING false

#define KILL_PIN P1_24 //After hitting the shutdown pin configuration

#define KILL_PIN_STATE true
