I2C real time clock (RTC) again.

Yee-Haw! I got it going. I looked at the i2c_board_info settings for one of the ARM chips (they are using a PCF8563 RTC). The setting is I2C_BOARD_INFO("pcf8563", 0x51) so I changed the flag data

from 68 to 51 and, as if by majic, it all works! Thanks Hippo, CB, Michael and all that worked on this. BTW I am using the OpenCores I2C interface instead of the I2C on GPIO. So that is tested now

too. Alex
