We need to make sure that accelerometer device which physically exists does not conflict with SD card in case of shared SPI. We reply on specific order of execution here: 1) accelerometer pre-initialization into safe CS pin state 2) SD card initialization 3) accelerometer main initialization if accelerometer feature is desired
