mb/compulab: Mark Intense-PC as single board computer in board_info.txt

Based on the pictures at http://www.fit-pc.com/web/products/intense-pc/,
the Intense PC does not look like a laptop. In its documentation it is
described as "mini-PC" or "Single Board Computer".

This patches moves the Intense-PC into the correct category on the
Supported Motherboards page.

Due to thermal considerations, I have not removed the "select
SYSTEM_TYPE_LAPTOP" in Kconfig.
