[PATCH V3 0/2 RESEND] ARM: dts: bcm283x: Fix probing of bcm2835-i2s

[Stefan Wahren]

This small series fixes the probing of bcm2835-i2s, which is broken
since 517e7a1537a ("ASoC: bcm2835: move to use the clock framework").

Changes in V3:
* split up patch into dt-binding and functional part

Changes in V2:
* add Fixes, Reviewed-by and Tested-by tags

[PATCH V3 1/2 RESEND] dt-bindings: bcm283x: Fix register ranges of bcm2835-i2s

[Stefan Wahren]

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.
