7d491aa015 Tiny improvement to M7219
The registers within the Max7219 can get corrupted a number of ways.  This allows the Max7219 to be reset and fully initialized.
And...  it also allows the user to see the initialization pattern.

Change Max7219_idle_task() routines to use single line if X-Axis has 16 or more LED's
Change Max7219_idle_task() routines to use single line if X-Axis has 16 or more LED's

This gets bugfix_1.1.x at parity with https://github.com/MarlinFirmware/Marlin/pull/11285 when it gets merged.

Support for multiple Max7219 units in a chain (#11226)
* Support for multiple Max7219 units in a chain

I'll move this support over to bugfix_2.0.0 in the next few days.   And
then look at updating the Max7219_idle() routine to make use of multiple
units in a chain.

* spelling correction

3505d018db Smarter MIN, MAX, ABS macros
Use macros that explicitly avoid double-evaluation and can be used for any datatype, replacing `min`, `max`, `abs`, `fabs`, `labs`, and `FABS`.

3f0b38ed5d Add Max7219 LED Matrix Debug Support (#7563)
* Add Max7219 LED Matrix Debug Support

The Max7219 8x8 LED Matrix's are very helpful for debugging new code.
And for that matter, just trying to maximize printer settings without
causing stuttering.

The displays are very inexpensive (under $2.00 with shipping) and
provide a lot of help when trying to debug complicated code.

* Try to keep Makefile up to date.
