Fix for the Split Common I2C code's SCL_CLOCK issue (#3474)
* Fix the SLC_CLOCK setting for the Split Common code
Make the SCL_CLOCK setting configurable per board, since some use different settings
And change the Iris to use 100000L instead of 400000L
* Add SCL_CLOCK variable to documentation
* Change SCL_CLOCK default to 100000L
