tegra132: return actual plld frequency
Depending on the requested frequency the plld cannot
necessarily obtain the exact clock. Therefore provide the
closest configured frequency as a return value. This is
equivalent to the t124 patch.
BUG=chrome-os-partner:31640
BRANCH=None
TEST=Built and noted plld actual value close to requested.
