[arch-general] Package group xorg-video-drivers: intel conflict

Since the addition of xf86-video-intel it has become impossible to install the xorg-video-drivers group via the group name (because of the conflict with xf86-video-i810). I guess there is no guideline outlawing this - I suppose something like this could, theoretically, happen more often. But it is a bit annoying when doing installations which are supposed to run on various machines. I don't want to make a request or anything here - I don't know what I could ask for. I just thought I'd point it out.
