Fixes a few issues with the rtc-ds1216 driver
- use rtc_valid_tm
- use platform_driver_probe
- fix init sequence - it was using rtc_unregister_driver where not
needed. I also added resource_size and removed an useless pointer
assignment.

Drivers should only need to implement either set_mmss (counter based RTCs)
or set_time (most RTCs). The RTC subsystem will handle them
appropriately.

Add standard interfaces for alarm/update irqs enabling. Drivers are no
more required to implement equivalent ioctl code as rtc-dev will provide
it.
UIE emulation should now be handled correctly and will work even for those
RTC drivers who cannot be configured to do both UIE and AIE.

A port of the existing x1205 driver under the new RTC subsystem.
It is actually under test within the NSLU2 project

It is the first driver under this new subsystem and should be used as a guide
