Subject: [PATCH v5 5/5] ACPI 2.0 / AML: Fix module level execution by correctly parsing table as TermList

This experiment follows de-facto standard behavior, parsing entire
table as a single TermList, so that all module level executions are
possible during the table loading.

If regressions are found against the enabling of this experimental fix,
this patch is the only one that should get bisected out. Please report
the regressions to the kernel bugzilla for further root causing.
