Revert commit 3130497f5bab (ACPI / sleep: pm_power_off needs more
sanity checks to be installed) that breaks power ACPI power off on a
lot of systems, because it checks wrong registers.
Fixes: 3130497f5bab (ACPI / sleep: pm_power_off needs more sanity checks to be
installed)

Hi Linus,
Can you take this for 3.14-rc6 directly so that the breakage is not present
in that -rc, please?
I obviously trusted the author of commit 3130497f5bab too much which I shouldn't
have done. My bad and sorry about this mess.
Rafael
