tests: acpi: don't read all fields in test_acpi_fadt_table() 



there is no point to read fields here but not actually
checking them so drop it and read only header + dsdt/facs
addresses since it's needed later to fetch that tables.

With this cleanup we can get rid of AcpiFadtDescriptorRev3/
ACPI_FADT_COMMON_DEF which have no users left.
