UmTRX dual-channel Rx

Hi all.

I found that both Rx divercity switches have zero state for A and B control inputs. Thus both LNA and LNA-D connectors are not switched to Rx inputs of the LMS's. To proceed Rx testing I suggest to set the next fixed states in the FPGA: DIVSW1_P = 1, DIVSW1_N = 0, DIVSW2_P = 1, DIVSW2_N = 0. In this case LMS1 will be switched to LNA connector, but LMS2 to LNA-D.

Andrew Karpenkov, would you please to make this kind changes, until DIVSW will controled by host?

Best regards, Andrey Sviyazov.
