[GIT PULL] DT clk binding support for 3.6

[GIT PULL] DT clk binding support for 3.6

[Rob Herring]

Mike,

Please pull DT clk binding and highbank clk support for 3.6. The only
real change from 3.5 pull request is returning error values rather than
NULL to align with the rest of the clk framework. There's been a little
discussion but otherwise has been quiet.

Hi Rob,

I agree that these patches have seen enough time on the list.  I did
find one problem in testing: the high bank clock registration function
writes to clk_hb->hw.init which is marked const.  I fixed it up in the
below patch.  That fix is now squashed into into the final patch in your
series on the clk-next branch.  Let me know if you have any objections.

Regards,
Mike
