There doesn't seem to be a build-time (or even runtime) dependency
between the two patches and they fix two independent issues, so they
could also go in separately.
I'm fine either way. From a Tegra perspective, the Tegra30 clock driver
is very low activity, so I don't expect any conflicts with between this
and some other patches that might go in through the clock tree.
