arm64: dts: renesas: white-hawk-single: cn3006: Add overlay for MSIOF2

Add an overlay to use MSIOF2 on the MSIOF2 Pin Header (CN3006) on the
White Hawk Single Board.

Use driver_override and bind to run the loopback tests:

    # echo spi-loopback-test > /sys/bus/platform/devices/soc/e6c00000.spi/spi_master/spi1/spi1.0/driver_override
    # echo spi1.0 > /sys/bus/spi/drivers/spi-loopback-test/bind
    [ test runs ]
    # echo spi1.0 > /sys/bus/spi/drivers/spi-loopback-test/unbind
