[PATCH 02/14] rtc: Ensure correct probing of the AB8500 RTC when Device Tree is enabled

[Lee Jones]

Without this patch, if Device Tree is enabled the AB8500 RTC wouldn't
get probed at all, as there is no reference to it from platform code.
This patch ensures the driver is probed during normal DT start-up.
