On platforms that do not have usable DRAM below 4GiB, like QEMU sbsa, the RSDT cannot be used. Allow both RSDT and XSDT to be null and only fill those tables that are present in acpi_add_table().
I'm not sure what ACPI 2.0 from the subject has to do with the above, eg ACPI only started supporting aarch64 with ACPI 5.1
Should perhaps be something like 'Support platforms without an RSDR'?
Fixes a crash on QEMU sbsa.

I was trying to see if this patch could be split into something which refactors the code and then another patch to fix the bug, but I can't see it.
