Revert "ACPI / bus: Parse tables as term_list for Dell XPS 9570 and Precision M5530"

Reverts commit 36904703aeee (ACPI / bus: Parse tables as term_list
for Dell XPS 9570 and Precision M5530).

Since commit 5a8361f7ecce (ACPICA: Integrate package handling with
module-level code), acpi_gbl_execute_tables_as_methods is always
true, so we can remove the quirk for XPS 9570/Precision M5530.
