spi: spidev: Add Pluto SDR compatible id

This patch adds an adi,swspi compatible id to the spidev driver. This is necessary in order to remove the warning that the DT is buggy. Others have implemented different options to take care of this see Raspberry Pi: a535fff (Completely disable the DT warning). Signed-off-by: Mircea <[email protected]>
