[PATCH RFC 11/12] thermal: step wise: fix kernel doc entry

[Eduardo Valentin]

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.
