[acpi] Add support for locating tables via the XSDT The ACPI XSDT is a 64-bit version of the RSDT, providing pointers to ACPI tables that may lie outside of the 32-bit address space. The only difference between the two tables is the size of the entries in the table pointer array. Add support for parsing the located root system description table as either a 32-bit RSDT or a 64-bit XSDT, with the 64-bit code paths optimised out via dead code elimination in 32-bit builds.
