Enabling external i2C RTC

Have managed to get things working with this RTC.

Am attaching small patch text to show what has been done as far as
code changes to board-omap3beagle.c
It was necessary to slow speed of 2nd bus from 400 down to 100kHz due
to clock specification. After that, very simple addition of i2c board
info structure and things are working great. Clock was not
initialised on first boot, but after issue a single hwclock -s
command, things are ticking over nicely!

regards,
