rtc: allow rtc_read_alarm without read_alarm callback

Browse source

[ Upstream commit a783c96261 ]

.read_alarm is not necessary to read the current alarm because it is
recorded in the aie_timer and so rtc_read_alarm() will never call
rtc_read_alarm_internal() which is the only function calling the callback.
