Testing this patch with PATCH 1/2, the twl_rtc driver fails to correctly
initialize on OMAP3:
twl_rtc rtc.22: hctosys: invalid date/time
instead of the expected result:
twl_rtc rtc.22: setting system clock to 2000-01-01 00:00:00 UTC
(946684800)
so something is still not right for the init sequence.
