RA8875 with Adafruit Display does not work about lovyangfx HOT 1 CLOSED

tl;dr
just add

0xc7      , 1, 0x01,  // set Extra General Purpose IO Register to Output (used to enable Display by Adafruit)

to

const uint8_t* Panel_RA8875::getInitCommands(uint8_t listno) const

inside Panel_RA8875.cpp right above PWM Setting.

The issue trouble me and left me no rest so I kept investigating. Aaaand after a few more hours I found the Problem! And, also as expected, it was something trivial but very hard to find. Adafruit uses on their RA8875 Board the GPIOX to Enable/Disable the Display (tiny ON/OFF label on Pin 46 in the schematic). These GPIO must be set to Output, otherwise the Display wont get the Signal to turn on. So just one register write solved the Problem.
