As dmtimer no longer exports functions, there is no point
to have them non-static. Also delete those not used anywhere.

I will refrain from this patch at the moment. I have plans of another
series to do some more cleanups. For now want to keep the changes minimal.

Some of the functions that you are removing in this patch might be
needed and can be added for ops in future.
So i will let this be separate patch.

Thanks,
Keerthy
