[Coco] Clock2 module for LR-Tech Superboard RTC for NitrOS-9

[Kandur]

Gene, we are not talking about the B&B-XT-RTC kits, 
nor the one Tony used on the SC-II+4in1, 
neither of the clock on the TC^3.

The LR-Tech Superboard has the HD1468 realtime clock chip.

Then please take a look at here, and read the code at the end too.
