RTC: add missing "return 0" in new alarm func for rtc-bfin.c

commit 8c122b96866580c99e44f3f07ac93a993d964ec3 upstream.

The new bfin_rtc_alarm_irq_enable function forgot to add a "return 0" to
the end leading to the build warning:
	drivers/rtc/rtc-bfin.c: In function 'bfin_rtc_alarm_irq_enable':
	drivers/rtc/rtc-bfin.c:253: warning: control reaches end of non-void function
