Lantiq Synchronous Serial Controller (SSC) SPI master driver

Required properties:
- compatible: "lantiq,ase-spi", "lantiq,falcon-spi", "lantiq,xrx100-spi",
  "intel,lgm-spi"
- #address-cells: see spi-bus.txt
- #size-cells: see spi-bus.txt
- reg: address and length of the spi master registers
- interrupts:
  For compatible "intel,lgm-ssc" - the common interrupt number for
  all of tx rx & err interrupts.
       or
  For rest of the compatibles, should contain the "spi_rx", "spi_tx" and
  "spi_err" interrupt.


Optional properties:
- clocks: spi clock phandle
- num-cs: see spi-bus.txt, set to 8 if unset
- base-cs: the number of the first chip select, set to 1 if unset.

Example:


spi: spi@e100800 {
	compatible = "lantiq,xrx200-spi", "lantiq,xrx100-spi";
	reg = <0xE100800 0x100>;
	interrupt-parent = <&icu0>;
	interrupts = <22 23 24>;
	interrupt-names = "spi_rx", "spi_tx", "spi_err";
	#address-cells = <1>;
	#size-cells = <1>;
	num-cs = <6>;
	base-cs = <1>;
};

ssc0: spi@e0800000 {
	compatible = "intel,lgm-spi";
	reg = <0xe0800000 0x400>;
	interrupt-parent = <&ioapic1>;
	interrupts = <35 1>;
	#address-cells = <1>;
	#size-cells = <0>;
	clocks = <&cgu0 LGM_CLK_NGI>, <&cgu0 LGM_GCLK_SSC0>;
	clock-names = "freq", "gate";
};
