Configure a TMC2240 stepper motor driver via SPI bus. To use this
Configure a TMC2240 stepper motor driver via SPI bus or UART. To use this
feature, define a config section with a "tmc2240" prefix followed by
the name of the corresponding stepper config section (for example,
"[tmc2240 stepper_x]").
