On many IDEX machines the allowed travel of the X1 carraige and X2 carraige does not perfectly overlap.

This helps the issue.   But more work needs to be done at the higher level.  (For example the X1_MAX_POS should probably be factored into G26's mesh validation pattern.)

As pointed out at https://github.com/MarlinFirmware/Marlin/issues/7981#issuecomment-407116642

Implement servo support for STM32F1. Original code was incomplete and depended on Servo library from stm32duino which conflicts with `module/servo.h`.

The `binary.h` file required by `lcd/dogm/dogm_bitmaps.h` is not present in stm32duino environment. Binary macros are defined in `bit_constants.h` in stm32duino framework.

Fix "SD init fail" problem for STM32F1 caused by incorrect SS pin state and incorrect SPI mode. Issue #11225

Some of the Rotations did not do the right thing with setting and clearing pixels.
I think it is correct now.   But if not...  It is much closer to being correct.

* Update ubl_G29.cpp

* Update ultralcd.cpp

Use a sector of the LPC flash memory to emulate EEPROM storage, removing the need to have an SD card to store system parameters.

- Clean up the API to use a `static` class instance to adhere to Marlin convention
- Add `const` position data access for read/write
- Add Storage capacity to the interface

Make M2719 initialize the Max7219 registers and then run the initialization pattern (if one is specified).

agData in Table 71 is extremely oversampled (see Issue #11220). I have removed the data points that perform *worse* than linearly interpolating the remaining points, and fixed up two points that were simply rounded incorrectly.
