    This patch removes the chip select function.  Chip select should instead be
    supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI
    core assert/deassert the chip select as it sees fit.
    
    The chip select control inside the controller is buggy.  It is supposed to
    automatically assert the chip select based on the activity in the controller,
    but it is buggy and doesn't work at all.  So instead we elect to use GPIOs.
