[PATCH] rtc-bfin: add missing "return 0" in new alarm func

[Mike Frysinger]

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
