spi: dt-bindings: add spi-{tx,rx}-lane-map properties

Add spi-tx-lane-map and spi-rx-lane-map properties to the SPI peripheral
device tree binding. These properties allow specifying the mapping of
peripheral data lanes to controller data lanes. This is needed e.g. when
some lanes are skipped on the controller side so that the controller
can correctly route data to/from the peripheral.
