I had a quick look at the other clock changes and there are a couple
of questions that have come up:

1) If changing the .id field of the iisv4 device really a good idea,
   especially if there might be more than one of them in the future?

2) The clock name for the current audio bus clock for the iisv4 unit
   is wrong as we're using it for both the iis and iisv4 blocks. It
   might be worth renaming the clock for the iisv4 audio bus before
   looking at changing the usage of the clock support (once the current
   changes have been sorted)

As such is the #ifdef of the clock code when the S3C6410 support
really necesary?
