Our current ACPI table generation code limits the placement of ACPI tables to 32-bit addressable memory, in order to be able to emit the root pointer (RSDP) and root table (RSDT) using table types from the ACPI 1.0 days. Since ARM was not supported by ACPI before version 5.0, it makes sense to lift this restriction. This is not crucial for mach-virt, which is guaranteed to have some memory available below the 4 GB mark, but it is a nice to have for QEMU machines that do not have any 32-bit addressable memory, which is not uncommon for real world 64-bit ARM systems. Since we already emit a version of the RSDP root pointer that has a secondary 64-bit wide address field for the 64-bit root table (XSDT), all we need to do is replace the RSDT generation with the generation of an XSDT table, and use a different slot in the FADT table to refer to the DSDT.
