ACPI: fix "acpi=ht" boot option

commit 49bf83a45fc677db1ed44d0e072e6aaeabe4e124 upstream.

We broke "acpi=ht" in 2.6.32 by disabling MADT parsing
for acpi=disabled.  e5b8fc6ac158f65598f58dba2c0d52ba3b412f52
This also broke systems which invoked acpi=ht via DMI blacklist.

acpi=ht is a really ugly hack,
but restore it for those that still use it.
