powerpc/4xx: Add suspend and idle support
Add suspend/resume support for 4xx compatible CPUs.
See /sys/power/state for available power states configured in.
Add two different idle states (idle-wait and idle-doze) controlled via sysfs.
Default is idle-wait.
cat /sys/devices/system/cpu/cpu0/idle
[wait] doze
To save additional power, use idle-doze.
echo doze > /sys/devices/system/cpu/cpu0/idle
cat /sys/devices/system/cpu/cpu0/idle
wait [doze]
