accelerometerChipSelect

OutputPin accelerometerChipSelect

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
