So: unfortunately the documentation there is pretty much all of the
documentation provided on the kernel side :P. However, I'm suddenly noticing
why that might be - going through the hrtimer headers again I'm noticing that
while we document all of the fields in hrtimer_clock_base, there's no publicly
exposed functions that interact with it. So, I don't really think we actually
want to expose it here either!

I'm going to rewrite this in the next series to not actually expose this
object at all, and instead just expose functions for retrieving the current
time from the base.
