acpi.c: Swap XSDT and RSDT for adding/finding tables
If ACPI is above 4G it's not possible to have a valid RSDT pointer in RSDP, therefore swap RSDT and XSDT. Both are always generated on x86. On other architectures RSDT is often skipped, e.g. aarch64. On top of that the OS looks at XSDT first. So unconditionally using XSDT and not RSDT is fine. This also deal with the ACPI pointer being above 4G. This currently never happens with x86 platforms.
