This reverts commit 5cf6a062e3.

Followup to #8814

* Adding support for using the MKS_12864OLED with the SSD1306 controller

* Update comment for correct controller type

[2.0.x] Support for Tronxy and Zonestar LCD

[2.0.x] Fix example configs and add to TravisCI tests - squashed

[2.0.x] V2 Extended NanoDLP_Z_Move_Sync to G4 & G28,Added all axis option.

[2.0.x] typo in Marlin.cpp

[2.0.x] Missing HAS_HEAT_BED conditional

Fixes issue found in #8779

[2.0.x] Comment, fix filament width sensor

[2.0.x] STM32F1 HAL: Fix issue #8585. Updates to readme.

* Fixing the DUE serial port assignments: Now -1 means the SAM3x USB Device emulating a serial port, and 0 means the USB to serial adapter included as a programming port

* Improving the Fast IO port access implementation on Arduino DUE

* Implemented EEPROM emulation on Due by storing data on the internal FLASH (with wear leveling)

* Implemented a Software SPI for the ST7920 graphics display for the Arduino RAMPS for DUE, as the default one in u8glib is clocking data too fast on ARM, and the display does not understand it.

* Fixing the case where the serial port selected is the USB device

* Adding configuration for the Makerparts 3D printer (www.makerparts.net)

* Tuned MakerParts acceleration on X and Y axis so it never loses steps. Also adjusted pulses per mm to match default hw configuration

* Fine tuned Maximum acceleration for MakerParts printer

* Style cleanup

* Style cleanup (2)

* Style fixes (3)

* Style cleanup

* Style changes to u8g_dev_st7920_128_64_sw_spi.cpp

* Even more improvements to the FastIO HAL for DUE. Now WRITE() is 2 ASM instructions, if value is constant, and 5 cycles if value is not constant. Previously, it was 7..8 cycles

* After some problems and debugging, seems we need to align the interrupt vector table to 256 bytes, otherwise, the program sometimes stops working

* Moved comments out of macro, otherwise, token pasting does not properly work sometimes

* Improved Software SPI implementation on DUE: Now it honors the selected speed passed to spiInit(). This allows much faster SDCARD access, improving SDCARD menus and reducing latency

* Update u8g_dev_st7920_128_64_sw_spi.cpp

* Disabling EEPROM over FLASH emulatiion if an I2C or SPI EEPROM is present

As reported in this issue:
https://github.com/MarlinFirmware/Marlin/issues/8585
I have it working fine in my local copy like that change.

[2.0.x] UBL - Skew and Dual X Carriage

Also remove unused grid slicing function when using UBL segmented.
