Exports to enable clock driver modules

Exports to enable clock driver modules

[Christoph Lameter]

The following exports are necessary to allow loadable modules to define
new clocks. Without these the mmtimer driver cannot be build
correctly as a module (there is another mmtimer specific fix necessary to
get  it to build properly but that will be a separate patch):

I'll convert these to EXPORT_SYMBOL_GPL, OK?

I'd say just disallow modular mmtimer instead.
