Reason: Default value of register needs to be changed for different applications

When using the SPI backchannel from the deserializer to two different slaves on two different boards, you will need to implement the SPI_LOC_ID. Each SPI slave needs to be assigned a different local ID. When an SPI packet is transmitted, the SPI_LOC_ID is included in the message and the SPI slaves filter the broadcasted messages by their ID. THE SPI_LOC_ID is programmed via I2C.
