Now that we have an extension to handle images, use it.

Signed-off-by: Mauro Carvalho Chehab mchehab@s-opensource.com ---

This patch is based on Daniel Vetter & Markus Heiser's work to support PNG and SVG via kpicture Sphinx extension:

[PATCH] docs-rst: automatically convert Graphviz and SVG images

v2: Don't use :caption:, as it doesn't exist on kernel-figure.

Unfortunately, this patch showed severl issues at the original patch. I'm still sending it, as it could help testing the issues there.
