Err.  This looks wrong.  What's the clk stuff doing in here?  It seems
to be completely unused by the driver, and then both PXA and SA1100
end up having to provide a 'dummy' clk structure to satisfy this
additional useless code.

If it's a case that "every driver must use a clk" then there's a policy
error somewhere.
