Same problem exists on on pxa3xx/cm-x300 and I suppose
on many other pxa based systems which use rtc-pxa and not
rtc-sa1100 (in which device_init_wakeup() indeed called before
the rtc_device_register()).

This patch makes /sys/class/rtc/rtc0/wakealarm visible and thus
solves the problem for cm-x300
