SSI block has two types of clock:

ipg: bus clock, the clock needed for accessing registers.
per: peripheral clock, the clock needed for generating the bit rate.

Currently SSI driver only supports slave mode and only need to handle
the ipg clock, because the peripheral clock comes from the master codec.

Only register the ipg clock and do not register the peripheral clock for ssi.

Applied and added stable tag (I assume this should go to stable, right?)

Yes, please apply v2 version and you can add the stable tag (only
applies to 3.5 stable branch though).

Thanks,

Yes I applied v2 (found it a bit later after writing the email)
