While trying to enable Octal SPI mode, it was observed that
SPI_RX_OCTAL/SPI_TX_OCTAL were not propagating into the spi_device
spi->mode setting.  This was causing the SPI device to always
operate in 1x mode instead of the desired 8x mode.

Please disregard.  This isn't quite right.  I'll resubmit a better patch
