Register SPI controllers through device tree. We will wire up the clocks
at a later stage.

++Binding for Broadcom BCM6348/BCM6358 SPI controller
++
++Required properties:
++- compatible: must contain one of "brcm,bcm6348-spi", "brcm,bcm6358-spi".
++- reg: Base address and size of the controllers memory area.
++- interrupts: Interrupt for the SPI block.
++- clocks: phandle of the SPI clock.
++- clock-names: has to be "spi".
++- #address-cells: <1>, as required by generic SPI binding.
++- #size-cells: <0>, also as required by generic SPI binding.
++
++Optional properties:
++- num-cs: some controllers have less than 8 cs signals. Defaults to 8
++  if absent.
++
++Child nodes as per the generic SPI binding.
++
++Example:
++
++	spi@10000800 {
++		compatible = "brcm,bcm6368-spi", "brcm,bcm6358-spi";
++		reg = <0x10000800 0x70c>;
++
++		interrupts = <1>;

+
+Add required binding support to probe through device tree.
+
+Use the compatible instead of the resource size for identifiying the
+block type, and allow reducing the number of cs lines through OF.
