[Intel-gfx] [PATCH 15/32] drm/i915: intel_pm.c: fix some ascii artwork at kernel-doc

Preserving ascii artwork on kernel-docs is tricky, as it needs
to respect both the Sphinx rules and be properly parsed by
kernel-doc script.

The Sphinx syntax require code-blocks, which is:

::

followed by a blank line and indended lines.

But kernel-doc only works fine if the first and the last line
are indented with the same amount of spaces.

Also, a "\" at the end means that the next line should be merged
with the first one.

Change the ascii artwork to be on code-blocks, starting all
lines at the same characters and not ending with a backslash.
