Revert "i386: use ACPI to power off the machine"

This reverts commit c031b41b783cc99c0bd5aac7d14c1d6e34520397.

Adding the ACPI parser from GRUB was a mistake as its license
conflicts with the one used by the legacy Linux drivers.  Furthermore,
adding support for ACPI to the kernel violates the minimality
principle.
