Add Einstart-S support (#11219)

Indeed the HAL does not need to be mucked around with to expose ATmega2560 pins not available as numbers on the MEGA board, I'll need to update the wiki with that tidbit and a reference to the pin-mapping comment in `fastio_1280.h`.

+## Einstart S Machine Notes
+
+The Einstart S is a commercial machine that ships with a proprietary firmware and "licensed" slicer program which requires the original SD card or license file (.lic/.reg) from support in order to function. The impetus for the port was that I acquired the machine on the weekend when tech support was closed.
+
+## Specifications:
+
+ - Powder coated, formed steel enclosure
+ - Machined Aluminum internal axis support frame
+ - Genuine matched HIWIN rails on all axis
+ - Genuine Minebea NEMA17 motors (200 steps/rev)
+ - THC7128 3A Stepper Drivers (configured for 16 microsteps, loud)
+ - 160x160 magnetically coupled non-heated bed
+ - PLA Only Direct Drive extruder
+ - SH1106 OLED Display w/ Cardinal navigation
+ - 9533 I2C PWM RGB LED Chassis illumination
+ - Onboard SD-Card Support
+
+## Initial modifications
+
+### Bootloader/Marlin installation
+
+This machine probably doesn't ship with the arduino boot loader, so unless you reflow a 2560 on there to replace the atmega1280 like I did (to preserve the original firmware), you'll need to use ISP to do an initial firmware load and/or bootloader flash!
+
+It's not that bad though, you can just buy an ISP programmer with the appropriate header, or build an ISP programmer using the Arduino ISP sketch (wiring is easier if you use the "old style wiring" which utilizes  the following pinout: (see the comments in the ArduinoISP sketch).
+
+I used an arduino Nano and a header I had lying around, but you could do the same with a nano and some dupont headers cut and soldered to the board, and taped/glued into a header.
+
+Triple check your pinouts, it shouldn't fry if connected backwards but if your pinout is wrong you're going to struggle for sure.

+## Uploading Marlin firmware to a stock Einstart S
+
+### Summary:
+
+Make, buy or steal a 10 pin ISP programmer and select the appropriate programmer option via Tools:Programmer in Arduino IDE, use the Sketch:Upload Using Programmer command or Shift-Ctrl-U (vs Ctrl-U to upload via serial).
+
+### Detailed procedure:
+
+You can either load Marlin directly via ISP programmer (easiest, but requires opening the chassis every time you want to change/update firmware)  or, just program the bootloader which will enable later uploads via USB. HOWEVER, to actually upload the sketch you will need one of the following:
+
+ - ISP programming header (ArduinoISP sketch, pinout below)
+ - OR
+ - Install bootloader on atmega1280 to enable native USB uploads (also requires ISP).
+ - AND
+ - Connect button between RESET and GND on ISP header, release post compile just before upload starts.
+ - OR
+ - Install permanent modification described below, requires no button press during upload.
+
+### Permanent modification to enable USB uploads via Arduino IDE
+
+As a permanent modification to enable direct USB upload from the arduino IDE, you would need to flash the boot loader using ISP first; but then you can solder a wire or 100n capacaitor between the DTR line on the FTDI to the reset line, which is conveniently located in several places on the board.

+
+With this modification you no longer need the reset button and you can program directly from the Arduino IDE.
+
+### Power notes during flashing.
+
+You do NOT need power connected when flashing via ISP.
+You DO need power when flashing via USB Serial but you MUST time the release of the reset line to allow the upload unless you've performed the permanent modification.
