[PATCH 04/10] RTC: Cleanup rtc_class_ops->read_alarm()

[John Stultz]

With the generic rtc code managing the now virtualized alarm timer,
no one actually calls rtc_clas_ops->read_alarm().

We do check that it exists in rtc_read_alarm(), but that is only
to verify that the hardware supports irqs. The same test can
be done by checking set_alarm instead.

This patch changes the the read_alarm check to set_alarm, and then
removes the read_alarm method and its implementations in the rt
drivers.

NOTE: I'm not 100% sure we won't later use this functionality from
the generic layer, so this patch should only go in after some
additional thought and discussion.
