drivers/rtc/rtc-twl.c: fix rtc_reg_map initialization



Initialize the rtc_reg_map in platform_driver's probe function instead at
module_init time.  This way we can make sure that the twl-core has been
already probed and initialized (twl_priv->twl_id is valid) since the
platform device for the RTC driver will be created by the twl-core after
it finished its init.
