FPGA: Dual channel mode (TX) was fixed.
FPGA: Multiplexer for the RX and TX frontends was added.

This was done due to the fact that the host can be able to work in dual channel mode.
FPGA: Work of each DSP channel's is indicated by separate LED's

LED A - Indicates the transmit status of the first transmit channel (LMS1)
LED C - Indicates the receive status of the first receive channel (LMS1)
LED E - Indicates the transmit status of the second transmit channel (LMS2)
LED B - Indicates the receive status of the second receive channel (LMS2)
