All Devboards can use the 32kHz counter as a RTC device.

Also delete the custom CMOS RTC header, which can be used for the
DS1693 on the PB1500.  But since it doesn't have a buffer battery
it is as useful as the on-chip RTC which I prefer.

au1200fb calls 3 functions which have to be defined in board code.
Fix this ugliness with the introduction of platform_data.
