[PATCH] fix voyager compile after machine_emergency_restart breakage

[James Bottomley <James.Bottomley@SteelEye.com>]

[PATCH] i386: Implement machine_emergency_reboot

introduced this new function into arch/i386/reboot.c.  However,
subarchitectures are entitled to implement their own copies of reboot.c
from which this new function is now missing.

It looks like visws will also need a similar fixup
