x86/ce4100: Fix reboot by forcing the reboot method to be KBD
The default reboot is via ACPI for this platform, and the CEFDK
bootloader actually supports this, but will issue a system power
off instead of a real reboot. Setting the reboot method to be
KBD instead of ACPI ensures proper system reboot.
