[arch-releng] New xorg drivers conflict

[Mr Green]

With the now release of xorg intel drivers, I am now unable to build 
archiso using xorg-drivers package.

Getting the following error:

Enter a selection (default=all):
resolving dependencies...
looking for inter-conflicts...
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: xf86-video-intel-sna and xf86-video-intel-uxa are in conflict

Can install drivers from a list [the plan at the moment].

More of a warning to other Iso builders ....
