spi: add multi_lane_mode field to struct spi_transfer

Browse source

Add a new multi_lane_mode field to struct spi_transfer to allow
peripherals that support multiple SPI lanes to be used with a single
SPI controller.

This requires both the peripheral and the controller to have multiple
serializers connected to separate data lanes. It could also be used with
a single controller and multiple peripherals that are functioning as a
single logical device (similar to parallel memories).
