Yes. kexec jump need to put devices into quiescent state and save
devices state into memory, which is implemented by calling hibernation
function: device_suspend(PMSG_FREEZE), whose implementation depends on
CONFIG_HIBERNATION.
So, I will add CONFIG_KEXEC_JUMP and select CONFIG_HIBERNATION
automatically.
