spi: Group cs_change and cs_off flags together in struct spi_transfer
The commit 5e0531f6b9
("spi: Add capability to perform some transfer
with chipselect off") added a new flag but squeezed it into a wrong
group of struct spi_transfer members (note that SPI_NBITS_* are macros
for easier interpretation of the tx_nbits and rx_nbits bitfields).
Group cs_change and cs_off flags together and their doc strings.
