spi: Add OF binding support for SPI busses This patch adds support for populating an SPI bus based on data in the OF device tree. This is useful for powerpc platforms which use the device tree instead of discrete code for describing platform layout.

of/spi: call of_register_spi_devices() from spi core code Move of_register_spi_devices() call from drivers to spi_register_master(). Also change the function to use the struct device_node pointer from master spi device instead of passing it as function argument.
