Remove the code to force ACPI to shutdown on CPU0

Browse Source 
It was discussed and introduced based on docs that some systems
need this to shutdown properly. I can find no mention of this in
ACPICA or ACPI docs.
This needs to be re-evalutad, as all my shutdowns been successful
after disabling it and I can't locate where this info came from
or if it actually helped.

See 1316462ab0fd0f25f7dbb7f23b607d981efd3edc for original commit
and bug 12306 on current shutdown issue.
