[PATCH] rtc: enable RTC framework on ARCH=um

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

There's no real reason it should be disabled, and at least we can
use it for development & testing with the RTC test driver.

However, two devices are missing a HAS_IOMEM dependency, so add
that to avoid build failures from e.g. allyesconfig.

Would there be objection to taking this through the linux-um tree?
I have a couple of patches that depend on it as well, to add
suspend/resume support with a pseudo-RTC to wake up from it.
