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 only fixes the affected dt-bindings.

Still looking for a DT ack, here.
