   *                         known compatible chips: A4982

   *                         known compatible chips: AD5206
   *    DAC_MOTOR_CURRENT_DEFAULT - used by PRINTRBOARD_REVF & RIGIDBOARD_V2
   *                         known compatible chips: MCP4728
   *    DIGIPOT_I2C_MOTOR_CURRENTS - used by 5DPRINT, AZTEEG_X3_PRO, MIGHTYBOARD_REVE
   *                         known compatible chips: MCP4451, MCP4018

   *  Motor currents can also be set by M907 - M910 and by the LCD.
