[U-Boot] [PATCH] at91rm9200: fix errors with CONFIG_CMD_I2C_TREE
This patch prevents linker error on AT91RM9200 boards, if CONFIG_CMD_I2_TREE is set. It implements i2c_set_bus_speed and i2c_get_bus_speed as a dummy function.

It's the same like first, but i2c_get_bus_speed returns CFG_I2C_SPEED instead of 0. I think this is the better value.
