I had a look as well and I think it is evil. In our case the RTC device is our
PMU which has a lot of wakeup sources (usb insert, remove, battery, power
button). You do not want to disable wakeup for the power button from userspace.

To make this somewhat sane (e.g. to only apply to the alarm), we will need to
add another (platform_)device for the rtc and make sure masking the alarm
interrupt is not undone by the suspend code of the pcf routine... or do other
evil things...
