x86: default to reboot via ACPI
Triple-fault and keyboard reset may assert INIT instead of RESET; however INIT is blocked when Intel VT is enabled. This leads to a partially reset machine when invoking emergency_restart via sysrq-b: the processor is still working but other parts of the system are dead. Default to rebooting via ACPI, which correctly asserts RESET and reboots the machine. This is safe since we will fall back to keyboard reset and triple fault if acpi is not enabled or if the reset is not successful.
