memory: tegra: Reword and correct comments

Fix incorrect comment on periodic_compensation_handler() as the call
update_clock_tree_delay() with DVFS_UPDATE is responsible for dividing
the samples accumulated up to that point and comparing the computed
values with the currently programmed ones. While at it fix the
indentation of a nearby comment.
