    power, xen64: fix PM_SLEEP build dependencies
    
    fix:
    
    kernel/built-in.o: In function `do_fork':
    : undefined reference to `refrigerator'
    kernel/built-in.o: In function `do_signal_stop':
    signal.c:(.text+0x1b076): undefined reference to `refrigerator'
    kernel/built-in.o: In function `ptrace_stop':
    signal.c:(.text+0x1b285): undefined reference to `refrigerator'
    kernel/built-in.o: In function `get_signal_to_deliver':

    kernel/built-in.o: In function `worker_thread':
    workqueue.c:(.text+0x212c1): undefined reference to `refrigerator'
    [...]
    
    as CONFIG_PM_SLEEP can now be enabled without CONFIG_PM.
