Removed i2cSetupActiveMasters from last the IPL Step.

The i2cSetupActiveMasters function was called during the last ipl
step in order to set the i2c bus speed to 400khz. This
functionality was determined to be redundant as the OPAL/PHYP code
initializes i2c bus speed. The call to i2cSetupActiveMasters has
been commented out for over a year.
