rtc: omap: fix missing wakealarm attribute
The platform device must be registered as wakeup capable before
registering the class device, or the wakealarm attribute will not be
created.
Also make sure to unregister the wakeup source on probe errors.
Fixes: 1d2e2b65d098 ("rtc: omap: restore back (hard-code) wakeup support")
