Since the move to the new clock framework with
commit 94cb7f76caa0b337 ("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 with the corresponding default
clock and rate.
