Orriginal MKS firmware on https://github.com/makerbase-mks/MKS-TinyBee also fails to compile if you enable MKS_MINI_12864_V3

You need to edit 1 file and add another missing file from MKS with edits.

Here is the diff for the edit on src/lcd/dogm/HAL_LCD_com_defines.h

Unzip this file add into Mrlin/src/HAL/ESP32/u8g_esp32_spi.cpp
u8g_esp32_spi.zip

This compiles, I have no way to test it,
It has a few warnings that relaly need to be looked at also..
