Since 517e7a1537a ("ASoC: bcm2835: move to use the clock framework") the bcm2835-i2s requires a clock as DT property. Unfortunately the necessary DT change has never been applied. While we are at it also fix the first PCM register range to cover the PCM_GRAY register. This patch also fixes the dt-bindings accordlingly.

I don't have the sound hardware to test the drivers function.
