Current rtc-omap driver expects the rtc module wake-up capabilities to
be set up by board specific code. However, in case of DT, this is not
possible.
So, add a DT property "ti,wakeup_capable" to indicate that the module
is wake-up capable.
Also, on some platforms (like AM33xx), a special register
(RTC_IRQWAKEEN) is available to enable Wakeup feature for Alarm Events.
Since new platforms/Boards are now added through DT only, this feature
is supported via DT property only. Platforms using such IP should add
the property "ti,has_irq_wake_enb" in rtc DT node.
