Add missing APU1 reference to x86 board.d

x86 board.d only contains a case for the APU2, not the APU1. This
causes, for example, network configuration not to be created correctly.
Even though the APU1 seems to reaching EOL, there a still a lot of them
out there.

The APU1 and APU2 is configured in the same way and this patch should
also be considered for stable, as the error also exists there.
