I have applied this to bcm2835's for-3.10/dt branch.

The BCM2835 has a single instance of the "SPI0"-type SPI master controller. Instantiate it in the SoC .dtsi file, Don't enable it in the Raspberry Pi board .dts file, since we have no idea what is actually connected, and hence no idea what to set the bus clock rate to.
