Mobile variants have a different pci id. Add it, and mark the previous
pci id as a desktop variant.

it seems this is wrong and desktop haswell SDPs are 8086:0c02, low end
mobile (?) is 8086:0c16 (which is currently in there marked as a
desktop version) and 8086:0c26 is high end mobile parts. can anyone
confirm that? I've only seen 8086:0c02 and 8086:0c26 versions and was
just assuming 8086:0c16 was desktop because it was marked as such but
that doesn't fit with the previous naming convention.
