This commit produces the same savings as the compiler options -fshort-enums. Except by setting the types manually we save also 2 bytes of SRAM.
By default, the enum type is 2 bytes, with we can explictly set it to one byte when applicable to reduce code size.
Almost all the savings from from 'enum Mode' in leds.h.
Change in memory:
Flash: -116 bytes
SRAM: -2 bytes
- rename stall*guard to StallGuard (match name with the vendor)
- separate TMC2130 module from EEPROM (they do not need to know about each other at all)
- separate SGTHRS settings from motion - moved to globals like all other "global" parameters
- improved EEPROM storage for SGTHRS
