The comment of initializing table header revision says: /* ACPI 1.0/2.0: 1, ACPI 3.0: 2, ACPI 4.0: 3 */ which might mislead it may increase per ACPI spec revision. However this is not the case. It's actually a fixed number as defined in ACPI spec, and in the laest ACPI spec 6.1, some table header revisions are still 1. Clean these up.
