Unfortunately CONFIG_ACPI_HT_ONLY outside and independent of CONFIG_ACPI
proved a bit confusing.
How about the more simple CONFIG_HYPERTHREAD or CONFIG_HT?
If enabled and CONFIG_SMP is set, then we will attempt to discover HT
via ACPI tables, regardless of CONFIG_ACPI value.
Or... (I know multiple people will shoot me for saying this) we could
resurrect acpitable.[ch], and build that when CONFIG_ACPI is disabled.
