LCD Screen corruption on certain config builds based on the given pins Monster8.h file #34

Occasionally my REPRAP SMART FULL DISCOUNT CONTROLLER LCD screen would completly garble on some rebuilds of this code base whislt porting it to my hardware.

I found issue https://github.com/MarlinFirmware/Marlin/issues/21778 which point me to the required LCD screen fix. I used the following changes to fix the problem -->

define BOARD_ST7920_DELAY_1 DELAY_NS(125)

#define BOARD_ST7920_DELAY_2    DELAY_NS(85)
#define BOARD_ST7920_DELAY_3    DELAY_NS(600)

It only takes a minor config change sometimes to cause the problem, in my case it was just adding in a KILL_PIN.
