I found the 'sleeptime_injected' variable now, which takes care of
forwarding the clock by the correct amount.

I also found the CLOCK_SOURCE_SUSPEND_NONSTOP flag next to it, which
should let us use the counter32k driver to provide the correct
time during suspend without the omap_read_persistent_clock() function.
We should be able to just delete that code.

If we decide to also delete the tegra_read_persistent_clock()
function, we can remove the registration too.
