spi: axi-spi-engine: support SPI_MULTI_LANE_MODE_STRIPE

Browse source

Add support for SPI_MULTI_LANE_MODE_STRIPE to the AXI SPI engine driver.

The v2.0.0 version of the AXI SPI Engine IP core supports multiple
lanes. This can be used with SPI_MULTI_LANE_MODE_STRIPE to support
reading from simultaneous sampling ADCs that have a separate SDO line
for each analog channel. This allows reading all channels at the same
time to increase throughput.
