[PATCH] Sanitize ACPI Kconfig

[Andi Kleen <ak-l3A5Bk7waGM@public.gmane.org>]

Sanitize ACPI Kconfig. No other subsystem uses default m for all its
options and surely there is no need to do this for the more obscure
modules. When you do make oldconfig with an old option and just press
return you tend to get a lot of modules you don't want with this. 
Normally new stuff is off by default.

I added default y for the processor driver which is important
for power saving, and for the others the user can decide but 
the default is off.

Also give a useful default for the cutoff year.
