boards: qemu_x86: properly enable XIP
The '#if XIP' in the DTS file never worked properly, causing the QEMU build to think it has much more RAM then it actually has. If RAM overflowed, this would not be caught by the build, instead there would be strange crashes when the data copy takes place. The QEMU targets themselves are not XIP, everything is actually RAM, but the first 4 megabytes are considered to be a memory-mapped flash region. This is done to ensure that the XIP data copying infrastructure doesn't bit-rot on x86. We are at the point where a lot of things depend on this, so just select it in the board Kconfig instead of enabling in the defconfigs.
