BCM2835 auxiliary peripheral clocks.

This is a followup to the main audio domain clocks series I just posted. There's a clock gate register controlling the clocks for a few extra peripherals, and Martin Sperl has been working on the SPI driver for 2/3 of them (the other is a simple UART). This gives those drivers the clock gate
