I2C connections

The I2C MUX is made from two TCA9548 I2C multiplexers. In Sayma RTM there are two main I2C busses: IPMI_I2C (from RTM connector) and RTM_FPGA_I2C. Each of them is connected to one multiplexer. Outputs are tied together, so masters (AMC board and FPGA) can access any of 7 I2C busses.
