This is a update to the I2C part of [PATCH] extended hardware support for MCF5282 (2006-11-30). This patch includes the orginal changes and adds i2c_get_bus_speed and i2c_set_bus_speed to use with CONFIG_I2C_CMD_TREE.

CHANGELOG:

* add hardware i2c driver for Freescale MCF528x * add i2c_get_bus_speed and i2c_set_bus_speed to use with CONFIG_I2C_CMD_TREE
