Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly. This is a cosmetic change to make
the code simpler and enhance the readability.

After the switch to devm_ functions and the removal of
rtc_device_unregister(), the 'remove' function does not do anything.

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d06310 ("device-core: Ensure drvdata
= NULL when no driver is bound"). Thus, it is not needed to manually
clear the device driver data to NULL.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

This patch converts the drivers in drivers/rtc/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

platform drivers, to re-enable module auto loading.
