x86/ce4100: Fix pm_poweroff
The CE4100 platform is currently missing a proper pm_poweroff implementation leading to poweroff making the CPU spin forever and the CE4100 platform does not enter a low-power mode where the external Power Management Unit can properly power off the system. Power off on this platform is implemented pretty much like reboot, by writing to the SoC built-in 8051 microcontroller mapped at I/O port 0xcf9, the value 0x4.
