rtc-omap: fix initialization of control register
As the comment explains, the intention of the code is to clear the OMAP_RTC_CTRL_MODE_12_24 bit, but instead it only clears the OMAP_RTC_CTRL_SPLIT and OMAP_RTC_CTRL_AUTO_COMP bits, which should be kept. OMAP_RTC_CTRL_DISABLE, OMAP_RTC_CTRL_SET_32_COUNTER, OMAP_RTC_CTRL_TEST, and OMAP_RTC_CTRL_ROUND_30S are also better off being cleared.
