Driver for the Atmel on-chip RTC on AT32AP700x devices

Tested on the AT32AP7000/ATSTK1000.  Driver does only suport time, wake up
and a very simple alarm, because of hardware limitations.

Hardware documentation can be found in the AT32AP7000 data sheet, which can
be downloaded from

http://www.atmel.com/dyn/products/datasheets.asp?family_id=682

From: David Brownell <david-b@pacbell.net>

 - Strike some alarm setup code that's no longer needed.
   (This patch seems to have gotten lost somewhere...)

 - Make the driver name (and its module alias) match what
   the platform setup code uses, so the driver can bind
   and hotplug.
