For Joonas basically. :)
Rough goal - add Kconfig options to turn off supported platforms and count on
compiler DCE to make the driver smaller.
Tested as so much that it boots and renders on Skylake with all platforms/gens
older than Gen8 turned off.

I've finished this today (all platforms plus some more details and
changes) but wont' post it again. Instead who is interested can see it
in my freedesktop git repo - people.freedesktop.org/~tursulin/drm-intel
platform-kconfig - but for some reason it is not showing in GitWeb any
longer.
Anyway.. with the latest build the i915.ko size goes from 15600073 to
1256697 when I enable only Skylake via Kconfig. This is 296kiB and close
to 20% saving.

Tvrtko
