[PATCH] i386 machine_power_off cleanup

Call machine_shutdown() to move to the boot cpu
and disable apics.  Both acpi_power_off and
apm_power_off want to move to the boot cpu.
and we are already disabling the local apics
so calling machine_shutdown simply reuses
code.

ia64 doesn't have a special path in power_off
for efi so there is no reason i386 should.  If
we really need to call the efi power off path
the efi driver can set pm_power_off like everyone
else.
