This patch adds the needed spi node for rk3036 dts.
We have to use the 4 bus emmc to work if someone want to support
the spi devices, since the pins are re-used by emmc data[5-8] and spi.
In some caseswe need to support the spi devices, that will waste the
emmc performance.
Moment, the kylin/evb hasn't the spi devices to work, so maybe we need wait
the new required to enable in kylin/evb board.
Anyway, the spi should be needed land in rk3036 dts.
