acpi/acpi.c: Fix regression with DSDT 

Fix regression introduced with commit 01af0f8ac8 ("acpi/acpi.c: Reduce boilerplate").

DSDT table is not to be listed within RSDT/XSDT, ACPICA and/or OSPM may
try load it twice raising conflicts in the namespace and effectively ignoring all or most of the AML.
