spi-geni-qcom: remove manual CS control
The GPI_DMA mode already uses automatic CS control, to use automatic CS
control for non-GPI case all that's needed is to set the FRAGMENTATION flag
using the same logic as setup_gsi_xfer(). (note clearing SPI_TRANS_CFG's
CS_TOGGLE bit enables automatic CS control, the comment was wrong)
spi_geni_set_cs() is slow, so this is a big performance improvement.
