rtc: omap: include header for omap_rtc_power_off_program prototype

[ Upstream commit f69c2b5420497b7a54181ce170d682cbeb1f119f ]

Non-static functions should have a prototype:

  drivers/rtc/rtc-omap.c:410:5: error: no previous prototype for ‘omap_rtc_power_off_program’ [-Werror=missing-prototypes]
