Hi Martin,

Since the move to the new clock framework with commit 94cb7f76caa0
("ARM: bcm2835: Switch to using the new clock driver support.")
the bcm2835-i2s driver was no longer working.

This patch fixes the address ranges:
* remove the PCM clock register range that is owned by the clockmanager
* fix the length, which did not include the last register of this device

It also adds the required pcm-clock.

this won't apply, because the file has been renamed to bcm283x.dtsi.

After applying clk series ([PATCH V4 0/7] clk: bcm2835: add clocks and 
add MASH support) and this series the pcm clock is an orphan.

Do we need to add "assigned-clocks" to the i2s node just like for pwm [1]?
