thermal: step wise: fix kernel doc entry

Update kernel doc entry and correct the format. Now
kernel doc does not complain about it.

In this change we reuse the comment that explain the
algorithm as a kernel doc entry. However, blank lines
are added, otherwise it will appear in a single paragraph
in the kernel doc output.
