From: Biwen Li <biwen.li@nxp.com>

This adds wakeup-source property to drop warning as follows:
    - $ hwclock.util-linux
      hwclock.util-linux: select() to /dev/rtc0
      to wait for clock tick timed out

My case:
    - RTC ds1339s INT pin isn't connected to cpus INT pin on T1024RDB,
      then the RTC cannot inform cpu about alarm interrupt

How to fix it?
    - add wakeup-source property and remove IRQ line
      to set uie_unsupported flag
