Commit 3b52093dc917 ("rtc: ds1343: Do not hardcode SPI mode flags") bit-flips (^=) the existing SPI_CS_HIGH setting in the SPI mode during device probe. This will set it to the wrong value if the spi-cs-high property has been set in the devicetree node. Just force it to be set active high and get rid of some commentary that attempted to explain why flipping the bit was the correct choice.
