device/*: replace old mesa-dri- dependencies with gallium
vc4 and freedreno have been provided by mesa-dri-gallium for a long time.
mesa-dri-intel subpackage has been deprecated for a while (previously dependend on dri-classic and dri-gallium)
mesa-dri-classic drivers is removed because mesa upstream has removed those old drivers from the tree. They've been replaced (for not-ancient hardware) by gallium.

@Minecrell has tested me176c with gallium driver in the past
I tested crocus already at some point, seemed fine then (didn't really feel any different)
Not 100% sure for surftab-wintron7.0 and our generic tablet-x86uefi? But given classic drivers are removed upstream there's not much alternative soon?
