[PATCH] lib/acpi: Enable QEMU special cases for ARM

With QEMU, we receive ACPI tables from the hypervisor rather than build
them ourselves in U-Boot. That logic however hard codes the target to the
x86 QEMU target, leaving ARM out on the fun.

Let's add the ARM QEMU config as well to the ifdefs so that we can consume
QEMU provided firmware tables there as well.
