Subject: [PATCH 8/9] spi: axi-spi-engine: remove delay from CS assertion

Now that the AXI SPI Engine driver has support for the various CS delays
requested through struct spi_message, we don't need to add a separate
delay to the CS assertion instruction. Otherwise, we end up with longer
than requested delays.
