ARM: tegra12: dvfs: Fix thermal limits comparison

When initializing CPU thermal limits profiles, original characterized
limits are compared with CPU DFLL minimum voltage already aligned to
PMIC ladder. This potentially may result in false negative outcome.
Fixed it by using non aligned minimum voltage as well.
