[PATCH v2 1/2] RTC: rtc-twl: Fix rtc_reg_map initialization

[Peter Ujfalusi <peter.ujfalusi@ti.com>]

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 it's
init.

Hi,

As Tomi commented on the first version:
www.spinics.net/lists/linux-omap/msg90064.html
www.spinics.net/lists/linux-omap/msg90066.html

I have separated the actual fix from the module_platform_driver() conversion.

Regards,
Peter
