[PATCH] rtc-cmos: use cmos_rtc_board_info to determine wake_on callback

[Marcelo Tosatti <marcelo@kvack.org>]

>From my understand ACPI fills a cmos_rtc_board_info with pointers for
wake_on/wake_off callbacks and registers that at dev->platform_data.

So use that to retrieve the callback pointers.

Am I missing something?
