No longer use custom property to define poweroff capability, use the standard DT property instead.

This is not acceptable. You may change all in-tree DTs to use the new property and also patch the driver to understand it, but you must make sure that the driver still understands the old, custom property. And especially in this case it isn't really hard to do.correct, it should be simple to hide that under of_is_system_power_controller() itself.
Guys, take a look at the code (PATCH 1/10). ;) Johan
