[v4,03/15] tests: acpi: make RSDT test routine handle XSDT

If RSDP revision is more than 0 fetch table pointed by XSDT
and fallback to legacy RSDT table otherwise.

While at it drop unused acpi_get_xsdt_address().

PS:
 it doesn't affect existing pc/q35 machines as they use RSDP.revision == 0
 but it will be used by followup patch to enable testing arm/virt
 board which uses provides XSDT table.

v4:
 * move out acpi_parse_rsdp_table() hunk to
   "tests: acpi: make pointer to RSDP  64bit"
   where it belongs
