[POWERPC] fsl_spi: stop using device_type = "spi"
Also:
- rename "fsl_spi" to "fsl,spi";
- add and use cell-index property, if found;
- split probing code out of fsl_spi_init, thus we can call
it for legacy device_type probing and new "compatible" probing.

ii) SPI (Serial Peripheral Interface)
Required properties:
- - device_type : should be "spi".
- - compatible : should be "fsl_spi".
+ - cell-index : SPI controller index.
+ - compatible : should be "fsl,spi".
- mode : the SPI operation mode, it can be "cpu" or "cpu-qe".
- reg : Offset and length of the register set for the device
- interrupts : <a b> where a is the interrupt number and b is a
